Lab report says weather, downturn of economy were not factors
By Allan Chen
BERKELEY, CA— It was California consumers – not mild weather or the cooling economy – who should get credit for avoiding blackouts and keeping the lights on in summer 2001. By embracing energy efficiency and conservation, consumers reduced their peak demand by 3,000 to 5,500 megawatts (MW), according to research by scientists at the Department of Energy’s Lawrence Berkeley National Laboratory.
This is the conclusion reached in a new analysis of the consumer response to the California electricity crisis by Charles Goldman, Joe Eto and Galen Barbose, researchers in Berkeley Lab’s Environmental Energy Technologies Division.
“Many observers predicted that California would face widespread rolling blackouts in the summer of 2001,” says Goldman. “In April 2001, the North American Electric Reliability Council predicted that the state would have about 250 hours of rolling blackouts. Others predicted that the cost of these blackouts would range from $2 billion to $20 billion. But the blackouts never happened last summer. Our research addresses the question of what role customer load reductions played.”
The report analyzes the effects of six factors on the reduction in load: (1) role of the media in increasing public awareness of the crisis; (2) electricity and natural gas price increases; (3) utility energy efficiency programs; (4) the 20/20 rebate program; (5) utility and California Independent Systems Operator (ISO) load management/ demand response programs; and (6) other state programs, such as energy use reduction by Federal, state, and local government facilities and partnerships with the private sector.
“Each of these factors contributed to customer load reductions to varying degrees,” says Goldman, “although separating the effects of one from another is difficult. For example, many customers may have qualified for a rebate through the 20/20 program by simultaneously taking advantage of an incentive for high efficiency appliances. The synergies between these various factors were an important reason that customer load reductions were as great as they were.”
In response to the state’s offer to rebate 20 percent on utility bills if consumers achieved a 20 percent use reduction – an offer that has been renewed for this summer — scientists in the Lab’s EET Division created the savepower.lbl.gov web site. It identifies energy-efficiency measures and their predicted percentage savings.
Goldman says customers responded to the electricity crisis through a variety of means: installing energy efficient equipment, installing onsite generation, and modifying their electricity consumption habits or patterns. “We estimate that energy efficiency measures and clean distributed generation will save the state about 1,100 MW when all the installations are completed from projects initiated during 2001,” says Goldman.
Some amount of the conservation behavior and changes in energy management practices will persist, depending on the continued awareness of energy issues and the sensitivity of customers to the increases in their electricity rates, he adds.
Eliminating Weather and Economic Factors
A central conclusion of the study is that consumer actions to reduce their electricity consumption were the driving force behind the load reductions observed in summer 2001 (load reduction means reduced demand for electricity).
“Some analysts argued that cooler than normal temperatures in 2001 lowered electricity use and peak demand compared to 2000,” says Goldman.
“We analyzed hourly temperature data from 122 weather stations throughout California, aggregated by county, and weighted according to population of the county. The analysis indicates that summer temperatures in 2000 and 2001 were almost indistinguishable, suggesting that weather was not a factor.”
Other analysts have suggested that the downturn in the California economy, including the collapse of the “Internet economy,” contributed to decreasing electricity use in 2001. “Economic indicators do not support this hypothesis,” says researcher Joe Eto. “Gross State Product is estimated to have grown 2.3% in 2001, and average employment during the summer months increased 0.8% compared to 2000.
Impacts of the Load Reduction
The researchers estimated the potential impact that these load reductions had on avoiding rolling blackouts in the state by combining detailed information on customer load reductions (reduced demand for power compared to the previous year) with information from the state ISO on aggregate demand (total demand for power in the state at any moment) and generation capacity (the amount of power available to California at any given moment), including the approximately 2,000 MW of generation capacity added during summer 2001 .
Rolling blackouts are usually ordered when the state’s excess power reserve to serve current demand falls below 1.5 percent. This is called a Stage 3 Emergency.
“We calculated the available operating reserve margin greater than 1.5 percent for every hour of the summer of 2001,” says Eto. “Our analysis showed that the customer load reductions maintained the operating reserve margin over 1.5 percent for between 50 and 160 hours, potentially avoiding rolling blackouts.”
Preventing Future Crises
An important lesson to take from this, according to the report, is that a pre-existing energy efficiency services infrastructure can help the state’s policymakers respond quickly to short-term power shortage emergencies. California was able to undertake massive energy-efficiency projects quickly because the underlying services were already there, due in part to the fact that the state’s policymakers and regulators have historically supported and funded energy efficiency programs.
“Another important lesson is that utility load management, demand response and retail pricing programs need to be re-designed well in advance of restructuring the electricity markets,” Goldman says. “California regulators and utilities essentially mothballed these programs during the transition to the restructured market.
“However, if a region does find itself facing a short-term crisis, the effectiveness of the load reduction programs in California demonstrates that such initiatives can contribute significantly to maintaining the reliability of the electric system,” he adds. “The $1.3 billion that California taxpayers and ratepayers invested in energy efficiency and demand response programs in 2001 was a good investment compared to the estimated $2-to-$20 billion in potential losses from rolling blackouts, not to mention the savings associated with avoided wholesale power purchases.”
This research will be published in the Journal of Industry, Trade and Competition. It is also available as an LBNL report 49733, “California Customer Load Reductions during the Electricity Crisis: Did They Help to Keep the Lights On?” by Charles Goldman, Joseph Eto and Galen Barbose.
Berkeley Lab Director Charles Shank will present his State of the Laboratory address to employees at noon on Tuesday, June 25, in the Building 50 Auditorium. The program will include a review of scientific highlights for the past year, plus a look into the future as it relates to budgets and programs. The talk will also be accessible via Internet broadcast.
The Director’s Address is the second event in this year’s Summer Lecture
By Ron Kolb
Lee Schroeder, during his seven years as Division Director in Nuclear Sciences, has seen the completion of some of the most significant projects in the field – the Solenoid Tracker at RHIC (STAR), the Sudbury Neutrino Observatory, even the Spallation Neutron Source now under construction for which he did some early work.
Now he puts a “period” on all of this with his own completion – he will step down as Berkeley Lab’s top manager in nuclear sciences. When Lab Director Charles Shank appoints his successor after a national search, Schroeder will return to his roots in accelerator-based research, where he first joined the scientific staff in 1971.
“The Nuclear Science Division has been enormously productive since Lee began as Division Director,” Shank said. The STAR detector at the Relativistic Heavy Ion Collider (RHIC) was successfully completed and began recording events, a major accomplishment for Berkeley Lab as well as for Brookhaven.
“Similarly,” Shank continued, “Berkeley Lab played an essential role in the development of the Sudbury Neutrino Observatory, which recently reported remarkable results verifying our understanding of energy production in the sun, and confirming that neutrinos have mass.”
He cited Schroeder’s positive influence on encouraging partnerships within the general sciences – Accelerator and Fusion Research, Nuclear Sciences, and Physics. Schroeder calls the nexus “making inroads at the intersections of particle and nuclear physics.” When the three division administrative offices physically merged in Building 50 a few years ago, he ordered a cake with the inscription “Grand Unification” on the top. He said he sees this as an expanding area, one he will explore in the next chapter of his career.
“Lee has been a wise leader, well respected throughout the nuclear science community, and he leaves a broad and strong legacy of accomplishment,” Shank added.
Schroeder points with pride to his pre-Director days, too. Some of his early work that he and others performed at the Bevatron/Bevalac eventually led to the broader scientific community’s interest in relativistic nuclear collisions at higher energies – the Alternating Gradient Synchrotron at Brookhaven, the Super Proton Synchrotron at CERN, and the dominant program at RHIC. “Tremendous advances in instrumentation and innovative uses of existing accelerator complexes allowed this to happen,” he said.
He also remembers a time back in the 1990s, following a 14-month assignment as Assistant Director for Physical Sciences and Engineering in the White House under Allan Bromley. When he returned to Berkeley, he was asked by the Department of Energy to assemble a group that could develop a “green” site design for a new neutron source. Today, a decade later, Oak Ridge is clearing ground for the $1.4 billion Spallation Neutron Source, the front end for which was just completed at Berkeley Lab.
What will he miss as he departs from the senior management team? “The dynamics of daily change,” he said. “But I look forward to being able to focus on one activity. I hope to find interesting science cases that can be carried out here at Berkeley with suitable accelerators, since these activities have been the legacy of this place.”
“I am confident,” Shank said, “that Lee will bring the same dedication and enthusiasm that has marked his term as Division Director. I greatly appreciate his service to the Laboratory and to the Nuclear Science Division.”

Daniel Chemla, who for the last few years has been Division Director for both Materials Sciences and the Advanced Light Source, has announced his intention to step down from the Materials position while continuing to lead the ALS Division. Berkeley Lab Director Charles Shank will begin a search process in the next few weeks to find a successor for Chemla in Materials Sciences.
“Since his arrival at Berkeley 12 years ago, Daniel has had an extraordinary impact on the Laboratory’s scientific programs and directions, in materials sciences and beyond,” Shank said. “From the beginning, he recognized the promise and importance of research on structures of nanometer dimensions, and he set a course to transform MSD into a world leader in the field.”
Shank called Chemla a “pioneer” in the exploration of nanoscience and said he will continue his role as visionary for the Department of Energy’s nanoscience initiative, including Berkeley Lab’s proposed Molecular Foundry.
“Despite the burdens of leadership, which Daniel has carried for the Laboratory, he is internationally recognized for his research accomplishments, and he is an active member of the Berkeley Campus Department of Physics,” Shank said.
Chemla took over the ALS Directorship in 1998 and since that time has been instrumental in developing the facility into a major international research center.
Shank now has the task of searching for four Division Directors in the next few months – in Materials Sciences, Nuclear Sciences, Genomics and Life Sciences.
LLNL’s Role in Homeland Security Unclear
“Our Lab has been cited in a number of media stories today relative to President Bush’s proposal to create a new Homeland Security cabinet level agency. We have not yet received any official details on this proposal.”
That was the official response of Lawrence Livermore National Laboratory to the proposal for a Department of Homeland Security in which, as stated in the published version, only about four-percent of LLNL’s 7,500 employees but 80-percent of its $1.5 billion annual budget would be transferred to the new department.
“Over the past few years, our Lab and our sister NNSA laboratories have played important roles in the war on terrorism and we look forward to enhancing our future contributions to this cause,” said out-going LLNL director Bruce Tarter. “At the same time, we remain committed to executing our core responsibilities of Stockpile Stewardship and our other federal programs.”
LLNL, like Berkeley Lab, is managed by the University of California for the U.S. Department of Energy. This makes it a GOCO, a government-owned/contractor-operated facility, which is common in DOE but would be the only one of its kind in the proposed Department of Homeland Security. At a recent press conference, Tom Ridge, the president’s director of homeland security, was unable to clarify what the Administration meant for LLNL in its proposal. He did, however, say that DOE for now would continue to oversee the LLNL research that pertains to nuclear weapons systems.
“We are not going to take over the traditional relationship DOE has had with Lawrence Livermore.”
Supreme Court Ruling Favors University Patent Rights
In a legal battle dubbed “the patent case of the decade,” the Supreme Court in a unanimous decision scaled back a lower court ruling that would have made patents held by research universities vulnerable to wholesale copying. This battle focused on a 150-year-old legal concept called the “doctrine of equivalents” which bars inventors from making minor changes to a patented technology and then claiming it as their own. The decade-old case involved a small company in New York that claimed a Japanese firm had infringed on its patent for a mechanical cylinder. Two years ago, a federal appeals court ruled that the doctrine of equivalents doesn’t apply to patent claims which were narrowed by the government during the review process, a common occurance for university patents.
The Supreme Court ruled that the appeals court went too far and that holders of narrowed patents should still be able to employ the doctrine of equivalents to fight infringement. Despite putting more of a burden on inventors to prove that a competing invention infringes on their discovery, the Supreme Court’s ruling is widely viewed as good news for university patents because it restores to judges the leeway to decide infringement claims on a case-by-case basis. — Lynn Yarris
On June 4, The University of California Board of Regents named Michael R. Anastasio, currently deputy director for strategic operations of the Lawrence Livermore National Laboratory and a research scientist nationally recognized for his leadership in the design and safe stewardship of nuclear weapons, as director of the UC-managed national laboratory.
Anastasio has spent virtually his entire career at Lawrence Livermore, starting as a weapons designer in 1980. He climbed through the ranks and is currently serving as the lab’s deputy director for strategic operations. He is scheduled to officially take the reins as the lab’s ninth director when the current chief, Bruce Tarter, retires July 1. However, he got to work even before that on June 11 when he and the directors of the other two U.S. nuclear labs will testified before a congressional subcommittee about the safety, security, reliability and performance of the nuclear weapons stockpile.
“Throughout a 22-year career at Lawrence Livermore, he has distinguished himself as both a brilliant scientist and skilled administrator with the right combination of theoretical and practical experience to maintain the laboratory’s historic place on the cutting edge of science,” said UC President Richard C. Atkinson.
“Mike Anastasio has a stellar reputation as a leader of the Lawrence Livermore weapons program,” said Lab Director Charles Shank. “He has a solid physics background and will be an asset to the Nation in certifying the stockpile. I look forward to working with him as part of the University management team of the laboratories.”
Recently, Anastasio, 53, has been a leader in the national Stockpile Stewardship Program (SSP) designed to sustain the safety, security and reliability of America’s nuclear weapons stockpile. He also has served in Washington as a scientific adviser at the Department of Energy, providing advice to senior members of the department on a variety of SSP issues.
In nominating Anastasio, Atkinson was advised by a committee of regents, research scientists and research administrators, which in turn was advised by an application screening committee consisting largely of the scientific leaderships of the Livermore laboratory and several UC campuses.
“I am honored to accept this appointment,” said Anastasio. “I have spent nearly 22 years at Livermore and I feel enormous pride in this institution and the people who work here.”
Anastasio and his wife, Ann, are residents of Livermore. They have two daughters in college, Alison and Alexandra. A sports enthusiast, Anastasio also plays the cello.
As director, Anastasio will oversee an operation with 7,500 employees and a $1.5 billion budget. He will earn $315,700 per year as director, the same as director Tarter’s salary.
On Saturday, June 22, friends and colleagues from around the world will gather at Bechtel Engineering Center for a day-long symposium marking Professor Chang-Lin Tien’s retirement from the university and honoring his research legacy and contributions to education and society.
For more than 40 years, as both a Mechanical Engineering professor and the former chancellor of the Berkeley campus, Tien has enriched the educational experience of the University of California while strengthening the University’s reputation around the globe.
Tien, who underwent brain tumor surgery in September 2000 and is receiving home care, will not be able to attend the event.
Those paying tribute to Tien during the afternoon program will include Chancellor Berdahl; UC Santa Barbara Chancellor Henry Yang; UC President Richard Atkinson and former President J.W. Peltason; Dan Mote, president of the University of Maryland and former Berkeley professor and vice chancellor; and the heads of the National Academy of Engineering, the Asia Foundation, and the Association of Pacific Rim Universities.
Members of the campus community are invited to attend the symposium. To register, or to submit a tribute to Tien, see http://www.me.berkeley.edu/tien.
W. Geoffrey Owen, professor and chair of the Department of Molecular & Cell Biology at the University of California, Berkeley, has been named dean of the Biological Sciences Division in the College of Letters & Science. He will assume the position July 1, taking the reins from Paul Licht, who held the post for the last eight years.
With about 105 faculty members in two departments - integrative biology and molecular and cell biology - the division houses researchers studying everything from entire organisms to the human genome. It graduates some 800 students each year who embark on careers in the health sciences, veterinary medicine, biotechnology, environmental science and academia.
“What Berkeley offers is a tremendous breadth of biology and a world-class faculty,” Owen says. “Our faculty really are tops; that’s why people come here.”
Owen, whose research involves how the visual system makes sense of the world around us, expects to spend much of his time raising funds to expand and improve biological research on campus.

Lawrence Berkeley National Laboratory,
A single instrument aboard SNAP, the proposed SuperNova/ Acceleration Probe, will make it unique among satellites: its billion-pixel astronomical camera, the GigaCAM. Built from an array of revolutionary Berkeley Lab CCDs developed by Stephen Holland and his colleagues in the Lab’s Engineering and Physics Divisions, the GigaCAM will be the largest and most sensitive astronomical CCD imager ever constructed.
Standard astronomical CCDs are fragile affairs, and their ability to obtain high-quality images degrades quickly in the hostile radiation environment of space — one reason why astronauts have already replaced all of the Hubble Space Telescope’s original imaging instruments.
“The Hubble and many other satellites were designed to be maintenance friendly, but SNAP is going to be placed in an unreachable orbit,” says Engineering’s William Kolbe, noting that once the GigaCAM is carried aloft on its five-year-plus mission, it can’t afford to fail.
At 300 microns (millionths of a meter) thick, the Berkeley Lab “high-resistivity, p-channel” CCDs are much more rugged than conventional astronomical CCDs measuring only a few tens of microns thick. In recent months Kolbe and Armin Karcher have been conducting tests at the 88-Inch Cyclotron to see just how well the new CCD can stand up to radiation damage.
Outer space in the lab
In space the culprits are cosmic rays, high-velocity particles packing a tremendous energetic punch that destroys pixels, increases “dark current” (a source of background noise), and worst of all degrades the efficiency of charge transfer from the pixels to the amplifiers at the edges of the chip. A few cosmic rays are massive atomic nuclei like iron, nickel, or zinc, but the majority are protons and electrons.
The 88-Inch Cyclotron simulates the cosmic ray environment with both heavy ions and protons, to test spacecraft components ranging from memory chips to transistors to entire computer systems, and to calibrate detectors used in compiling space “weather” reports. CCD chips and solar cells are particularly prone to degradation from large numbers of protons generated during high solar activity.
“At the Cyclotron, protons are delivered to target components at the Light Ion Irradiation Station located in Cave 3,” says Peggy McMahan, research coordinator for the 88-Inch Cyclotron. “We owe this station to a group from the Life Sciences and Engineering Divisions, who worked with our operations staff to develop it in order to maintain a small radiation biology program here after the closure of the Bevalac in 1993.”
In the station the dose is measured and the beam is “blown up” to four inches in diameter to uniformly irradiate silicon wafers (and the Petrie dishes used in Life Sciences experiments too). The Materials Sciences, Chemical Sciences, and Advanced Light Source divisions have also used the irradiation facility when the cyclotron is not busy with nuclear science experiments, its primary mission. Companies who have tested components for space applications on a fee basis include Eastman Kodak, Aerospace Corporation, Lucent Technologies, and Mitsubishi Electronics.
Test CCDs for the SNAP project are bombarded with beams of protons ranging in energy from 10 to 55 MeV (million electron volts); by testing several wafers, each at a different dose — from a few billion to a hundred billion protons per square centimer of surface — dosage can be scaled to equal what CCDs would receive after several years in orbit.
Before irradiation, Kolbe and Karcher assess the test wafers in their laboratory for dark current, charge transfer efficiency, and “cosmetic” defects. Computer processing and other electronic tricks can compensate for cosmetic flaws like a few damaged (“hot”) pixels, endemic to all CCDs, but dark current and charge transfer efficiency pose more serious challenges.
Dark current is electronic noise caused by thermal motion of the atoms that make up the chip; the colder the chip, the less the dark current. The Berkeley Lab CCD is much thicker than ordinary astronomical chips so there is more material in which dark current can be generated, but its high purity, negative “doping,” and low operating temperature work to suppress dark current. In space, SNAP’s GigaCAM will operate at about 140 degrees Kelvin (by comparison, nitrogen under normal atmospheric pressure liquefies at 77 deg K).
Typically the most serious radiation damage to CCDs is a steady reduction in charge transfer efficiency. Photons from distant objects like stars are focused on pixels in the CCD, and the brighter the object, the more photons are converted to charge. Negative electrons or positive “holes” are collected and transferred to the edge of the chip along specific channels, like buckets of water in a bucket brigade. The chip’s electronics reconstruct the image of a star by associating the precise amount of charge and the precise location of the pixels that generated it.
“When you irradiate a CCD with protons, silicon nuclei are knocked out of their lattice position, and what was fairly perfect material develops defects,” Kolbe says. “These form electron or hole ‘traps’ that can grab charge that’s being transferred, hold onto it for a time, then let it go later.”
Armin Karcher notes that these inefficiencies in charge transfer “can affect the apparent brightness of objects in the sky and the interpretation of their spectra.” The success of the SNAP satellite will greatly depend on its ability to measure supernova spectra with extreme accuracy.
To characterize the test CCDs, Kolbe and Karcher create star fields by exposing them to a small x-ray source. “Each x-ray photon deposits an artificial ‘star’ every 50 to 70 pixels, generating a cloud of charge,” says Karcher. “We know how many electrons it takes to represent each of these, so when we read out the data we know what the reading should be.”
And the winner is . . .
After irradiation at the 88-Inch Cyclotron, Kolbe and Karcher take the test wafers back into the laboratory to measure radiation effects from different doses. In the three batches tested so far they found that, while radiation dosage increased dark current, the effect was important only at high temperatures — and the impact of radiation on charge transfer efficiency was remarkably small. Available studies indicate that the charge transfer efficiency of conventional CCDs falls off rapidly with increased radiation, while the Berkeley Lab CCDs are little affected even at very high doses.
These results were not unexpected; after all, the Berkeley Lab CCD descends from a long line of detectors designed to withstand radiation from colliding beams of particles in giant research accelerators — “much more hostile than outer space,” Kolbe remarks.
“The high-resistivity p-channel CCDs exhibit extremely low dark current at the operating temperature,” the researchers concluded in their latest report. “Radiation damage proved to be much less detrimental than in conventional CCDs. . . . Their potential lifetime in space is measured in decades, not years.”
Kolbe and Karcher have devised new instruments to test larger CCD wafers, to measure the efficiency of their response at all wavelengths, and to investigate what effect pixel size, different levels of doping, and other manufacturing variables may have on their performance after radiation exposure.
“We’re expanding our capabilities constantly,” Karcher says. “We plan to keep going till SNAP flies.”

While his work in accelerator modeling on supercomputers definitely puts his professional life in the fast lane, Andreas Adelmann and his family are finding it a challenge to adjust to the fast-paced Bay Area lifestyle.
Selected as the first recipient of NERSC's Luis Alavarez Postdoctoral Fellowship in Computational Science, Adelmann, his wife and three children recently moved into a home in North Berkeley. In their native Switzerland, they lived in Lenzburg, a town of about 8,000, 15 miles west of Zurich.
"This area is so busy, with everybody rushing around," Adelmann said. "It's kind of a culture shock."
"Although he is an early-career scientist who just finished his dissertation this past summer, Andreas is already one of the leading researchers in Europe developing the tools for large-scale simulation of accelerators using parallel computers," said NERSC Division Director Horst Simon. "With his background and experience, he is a perfect match to connect NERSC the Accelerator Modeling SciDAC project and we expect him to make contributions to the progress of this project."
Adelmann is working with Robert Ryne and Esmond Ng in NERSC's Scientific Computing Group to model next-generation accelerators as part of DOE's Scientific Discovery through Advanced Computing (SciDAC) Accelerator Physics Project. Ryne had developed codes for modeling linear accelerators, while Adelmann has modeled circular accelerators.. Their codes have the same goal of accurately modeling beams and they are using the two models to try to achieve the same results.
Adelmann did his doctoral thesis at the Eidgenoessischen Technischen Hochschule (ETH) while working at the Paul Scherrer Institute in Switzerland. The institute-comparable to a national laboratory-operates proton cyclotrons and an electron light source. Adelmann earned his Ph.D. in mathematics from the ETH.
In the previous issue of Currents, our article on the Friends of Science program contained an error. As Eva Nogales has pointed out to us, the work that ended with the atomic structure of tubulin was not carried out in her lab, rather in the lab of Ken Downing where she worked as a postdoc under Downing’s supervision. We apologize for the confusion.
Neville Smith, Director of Science at the Advanced Light Source, escorts a group of Norwegians on a tour of the ALS. The 16-member group consisted of representatives from the Norwegian Research Council, which is convened under Norway’s Department of Medicine and Health. Their five-day Bay Area tour focused on molecular biology in medicine, ranging from basic research to patient treatment. At the Lab they learned about protein crystallography and cell biology research at the ALS. The group also met with Dr. Thomas Budinger, Head of Nuclear Medicine and the Center for Functional Imaging, and learned about Berkeley Lab’s research in positron emission tomography (PET) and functional imaging.
David Bailey, chief technologist at NERSC, will kick off Berkeley Lab’s annual Summer Lecture Series on June 18 with a presentation on “Are the Digits of Pi Random?” The series will continue the following five Tuesdays at noon in Building 50 auditorium, including Director Shank’s State of the Lab address on June 25.
The one-hour lectures are geared to a general audience and are open to all Lab employees, summer students, teachers, and visitors. Audience members are welcome to bring their lunches to the talks.
Bailey’s research has included studies in parallel computing, numerical analysis, fast Fourier transforms, multiprecision computation, supercomputer performance, and computational number theory. Bailey, along with his colleague Richard Crandall, director of the Center for Advanced Computation at Reed College in Portland, Oregon, has taken a major step toward answering the age-old question of whether the digits of pi and other math constants are “random.” Their results were reported in the Summer 2001 issue of Experimental Mathematics.
Following the State of the Lab, the Summer Lecture Series will continue on July 2 with physicist Peter Nugent of NERSC speaking about his research using the Hubble telescope. Next up is Keith Jackson, leader of the lithography programs at the Center for X-ray Optics, on July 9 discussing the deep-etch lithography technique known as LIGA and its role in nanotechnology advancements. The lecture on July 23 will feature Ashok Gadgil and his recent work developing a Building Occupant Protection Guide as one of the Lab’s efforts to assist DOE’s Homeland Security efforts. The July 16 speaker will be announced in the next issue of Currents.
Berkeley Alert! Berkeley Lab scientists worked with Livermore Lab to prepare this realistic — but completely fictitious — map of a plume of toxic chemicals spreading east northeast across part of the city of Berkeley and the University of California on the morning of June 6, after a crop-duster loaded with pesticides supposedly crashed into a building at Shattuck and Center. Emergency personnel from five agencies including the Lab, the city, the university, Alta-Bates Summit Medical Center, and the Bayer Corporation — who also suffered a simulated hostage situation during the busy morning — participated in a two-hour exercise to practice joint response to a terrorist strike against the Bay Area. “This is the first time so many agencies have worked together to practice coordinated response management to a terrorist threat,” according to Berkeley City Manager Weldon Rucker. Throughout the months-long development of the Berkeley Alert exercise, Berkeley Lab’s participation was coordinated by Valerie Quigley of the Environment, Health, and Safety Division. — Paul Preuss

First Day of Summer Celebration
According to the calendar, summer arrives on Friday, June 21. And although recent hot weather might convince you otherwise, Berkeley Lab’s musicians and car enthusiasts will do their best to pay homage to the official solstice, as Nature intended.
During the noon hour on the first day of summer, Lab employees are invited to celebrate the vacation season. Kevin Bradley of Engineering has assembled almost two dozen classic cars and hot rods for display in the lower Cafeteria parking lot. And Steve Blair of Facilities has pulled together the Berkeley Lab Rhythm and Blues Band to offer sounds of the summer on the cafeteria outdoor stage.
As further evidence that the picnic season has arrived, the cafeteria catering service will offer outdoor barbecue specials on hamburgers, hot dogs and ice cream sundaes.
Bradley, a classic car enthusiast, said he and his lab colleagues will line up the polished, historic cruisers and coupes for inspection by employees – in most cases, hoods up and doors open. They will be on display from 11:30 a.m. to 1:30 p.m. Today’s the last day to register a car for inclusion in the rally; call Bradley at X4319, or e-mail him to arrange an exhibition spot.
“First Day of Summer” is sponsored by the Berkeley Lab Employee Activities Association.
Breast Cancer Forum Addresses Aging
On Friday, June 28 at Noon in the 50 Auditorium, the Berkeley Lab Breast Cancer Research Awareness Forum will host its June installment entitled, “Breast Cancer and Aging.” The event will feature two prominent breast cancer investigators, Lab Staff Scientist Judith Campisi Ph.D. and Christopher Benz M.D. of the Buck Institute.
Campisi recently joined the faculty of the Buck Institute while maintaining her research lab on the hill. The primary focus of her research is to understand the cellular and molecular basis of aging. Additionally, she is studying the mechanisms responsible for the normal, premalignant and malignant phenotypes of breast epithelial cells.
An internationally recognized expert in the field of breast cancer research, Christopher Benz joined the Buck Institute in September of 2000 from UCSF. As the Director of the Program on Cancer and Developmental Therapeutics at the Buck Institute, Benz focuses on identifying molecular strategies to improve cancer diagnostics and therapy, giving special emphasis to breast cancer. He is also an active member of the UCSF Comprehensive Cancer Center’s Breast Oncology Program and remains clinically involved at the UCSF Breast Care Center.
