Downtown Building to Be Occupied in May

Express shuttle bus will service Berkeley Tower

By Monica Friedlander

Beginning on Monday, May 10, a number of Lab groups and departments will start moving to a new building leased by Berkeley Lab in downtown Berkeley. The move is part of an effort to consolidate various off-site administrative functions at one location.

The building, known as the Berkeley Tower, or Bldg. 937, is located as 2120 University Avenue, at the corner of Shattuck Avenue.

About 200 Lab employees will be affected: current occupants of the Hinks Building (Bldg. 936) - CFO, Budget, Travel, Property, Management, Accounts Payable, and Internal Audit Services; Procurement and Administrative Services employees now located in Bldg. 69 and Bldg. 65, respectively; and Lab occupants of the downtown Promenade Building (Bldg. 938) - Information Systems and Services, Human Resources, Center for Science and Engineering Education, and Work Force Diversity.

According to Lawrence Wolfsen of the Facilities Planning Group, the amount of space allocated will not change. "But it will be better space," he says. "Everything will be centrally located, in a modern, more secure building, and employees will be able to work together more conveniently and efficiently. If Human Resources people need to work with someone in Financial Services, for example, they won't need to walk across town. All off-site people will be in the same building."

First to move the week of May 10 will be occupants of the Promenade Building, starting with ISS and HR employees. Off-site employees to move to the Hill are those in CSEE, who will move from the Promenade to Buildings 29B and 7, and the Property Management group, who will join the Facilities Department and move to Bldg. 69.

Financial services and other occupants of the Hinks Building will move on May 17. The move will conclude on June 7 with Procurement and ASD employees moving downtown.

Parking spaces have been reserved for Berkeley Tower occupants in two nearby parking garages on Allston Way and Kittredge Street.

A special dedicated bus will shuttle Berkeley Tower employees both to and from the garages and to the Hill. During the commute hours (before 9 a.m. and after 4 p.m.) the shuttle will run a small loop every ten minutes between the two garages and Berkeley Tower.

After 9 a.m. and until 4 p.m., the express bus, running at 20-minute intervals, will pick up employees at the downtown building and take them directly to any desired location on the Hill. To return downtown, employees will be picked up at the regular bus stop next to Bldg. 65. After 4 p.m. they may ride the regular off-site shuttle bus, get off at Oxford Street, and walk half a block to Bldg. 937.

Further information about the move and shuttle service will be made available in future issues. For more information, contact Berkeley Tower Project Manager Bill Wu at X5216.

Gamma-Ray Camera Will Take Snapshots Of Contaminated Buildings and Sites

By Paul Preuss

You don't need a lens to form an image with light, as any kid who has made a shoebox camera with a pinhole stuck through a bit of aluminum foil can tell you. Photons passing through the tiny aperture nicely distribute themselves into an image on a flat surface a few inches away.

If the photons happen to be gamma rays, passing them through a pinhole is one of the few ways you can get them to form an image at all. "Unlike visible light, gamma rays are highly penetrating and can't be focused with lenses," says Paul Luke of the Lab's Engineering Division. "But they can be allowed to pass through a pinhole onto a position-sensitive detector to produce an image."

Recently the impetus to build a better gamma-ray camera has come from the Department of Energy's Environmental Management Science Program, which wants such a device for imaging radioactive materials in contaminated buildings and waste sites. Luke and his colleagues, drawing on their experience crafting gamma-ray and x-ray detectors for use on spacecraft, medical scanners, synchrotron beamlines, and other scientific instruments, have built detectors with improved position sensitivity, efficiency, portability, and suitability for use at high energies.

Their goal is to build high-performance cameras that can take pictures of potential radioactive sources and at the same time identify just what kind of hot stuff is in them.

"Germanium detectors have good energy resolution for isotope identification," says Luke, "so in addition to imaging the source, by measuring the energy of the incident gamma rays you can identify the isotopes that emitted them."

With W. Neil Johnson and others at the Naval Research Laboratory, Luke designed a prototype 2-D, position-sensitive germanium detector using a coded-aperture imaging method, in which a computer algorithm reconstructs an image from multiple pinholes in a predetermined pattern. The principal advance, however, was a new detector-electrode fabrication technology. Says Luke, "Most germanium detectors in the past had poor or no spatial resolution because of difficulties in making highly segmented electrodes."

In the new process, a layer of amorphous germanium is sputtered onto the pure germanium crystal; thin-film metal contacts are applied by evaporation through a mask to form the segmented electrode pattern. Luke says, "Not only are these contacts easy to produce, they can be used on both sides of a detector, replacing the usual contacts made by doping the crystal with different impurities."

Luke and his colleagues built a detector with contacts on two opposing sides. The contacts are divided into strips a couple of millimeters wide, with the strips on one side running at right angles to the strips on the other. Electrical connections are made at the end of each strip. When a gamma ray photon strikes an electron in the detector, the electron moves through the germanium crystal and creates a tiny cloud of electrons and holes (positive charges). In an electric field these migrate in opposite directions, charging a single strip from each detector side so that the event can be assigned x and y coordinates.

While the 2-D detector can be used to image gamma rays, image resolution is far from ideal. The charges from the strip electrodes provide two-dimensional localization and energy information, but it is hard to pin down the precise depth of the initial gamma-ray absorption -- especially since gamma rays are deeply penetrating, and the detector must be thick enough to stop them.

"To reduce the image degradation caused by Compton scattering, parallax, and other effects, we need information about the third dimension," says Mark Amman of Engineering, who is working with Luke on a "depth-of-interaction" sensing technique.

"We effectively divide the detector into thin layers by looking at the timing characteristics of the strip signals," Amman explains. "When gamma rays enter and are absorbed, the collection times of negative and positive charges from the absorption events vary with depth, so the shape of the signal tells us how deep the interaction was." By knowing accurately where the gamma ray is absorbed in the detector in 3-D, a much sharper image can be reconstructed.

Cryogenic cooling presents another obstacle to a highly portable gamma-ray camera. "Only germanium can give you high energy resolution," Luke explains, but unfortunately germanium detectors have to operate in a vacuum at the temperature of liquid nitrogen.

"We can get rid of the nitrogen reservoir if we can use a mechanical cooling system; Norm Madden and Chris Cork, working in another group here in Engineering, have recently tested detectors with cooling systems that are portable. They seem to work just fine."

Under DOE's Environmental Management Science Program, Luke, Amman and their colleagues are developing the techniques needed to realize the 3-D detector. At the same time they are working on detectors with even better resolution.

Their goal is a high-resolution gamma-ray camera portable enough to be carried around possible sites of radiation contamination. The next challenge is the fabrication of a complete working model.

Lab Scientist Will Lend a Hand to Test Ban Treaty

By Jon Bashor

Verifying compliance with the Comprehensive Test Ban Treaty presents a host of technical and political challenges.

While the political issues involving the more than 150 nations signing the treaty are being handled in the diplomatic arena, Berkeley Lab's Deb Agarwal is lending her technical expertise to helping overcome technological hurdles.

Since taking on the assignment earlier this year, Agarwal of the Information and Computing Sciences Division has traveled around the country to meet with experts in the fields of sensor data collection, storage, transmission and authentication. The next stop on her itinerary is Vienna, headquarters of the Comprehensive Test Ban Treaty Organization, where she will be staying for the next three months.

Her immediate task there will be to serve as an independent expert and to help the organization determine if "reliable multicast" technology is a cost-effective way of handling the large amount of data involved in verifying that no nation detonates a nuclear device. If the technology is deemed appropriate, Agarwal will then help specify a communications protocol for the international monitoring system.

Agarwal wrote her Ph.D. thesis on reliable multicasting, and has been providing reliable multicast service to the DOE collaboratories for the past four years. But assessing whether the technology could work effectively on a global scale for verification of the treaty is a significantly different problem.

"The more I become involved, the more I learn," she says. "I could end up having a significant impact on how the communications system is built to verify that no one conducts another nuclear test. That's cool!"

IP mulitcasting, or the transmission of a single data stream to several different sites, can provide an efficient mechanism for transmitting data. It is, however, based on the "best effort" concept, and data does get lost - something which is unacceptable for treaty verification. "Reliable multicasting" provides a layer of reliability by retransmitting when data is lost, and by having systems in place for avoiding network congestion.

Although a number of federal agencies are contributing to the technology needed for treaty verification, they also realized that multicast expertise was needed. Stu Loken and Bill Johnston of Berkeley Lab were contacted, and they recommended Agarwal.

"Deb has brought tremendous energy and expertise to the collaboratory program and especially to the multicast area," said Loken, director of the Information and Computing Sciences Division. "It's great to see her work being recognized in this important international project. What she learns in this new effort will be of great benefit to the collaboratory and to the Strategic Simulation Initiative projects as well."

Building the monitoring network

The challenge in building the international monitoring system is to link some 337 monitoring stations around the globe. These include arrays of sensors designed to measure and transmit data about seismic, hydroacoustic and infrasound events and evidence of radionuclides.

Although all the data will be transmitted, stored, analyzed and disseminated from the International Data Center in Vienna, some nations have asked that they also receive all the raw data simultaneously. Reliable multicasting, Agarwal says, has the potential to meet both needs, as well as to circumvent the possibility of having the entire system crash if the Vienna center fails.

The global array of sensors in the atmosphere, oceans and underground will detect a wide range of activities, such as nuclear blasts, earthquakes, lightning, meteors hitting earth, and mining explosions. Data from these events, expected to number from 100 to 500 per day, will then be analyzed to determine the time, location and probable cause. The treaty organization will issue bulletins containing both raw and analyzed data. If a suspicious event cannot be resolved through consultation and clarification, each nation signing the treaty has the right to request an on-site inspection.

Various U.S. organizations are helping to pull all of this information together. Sandia, Los Alamos, Pacific Northwest and Lawrence Livermore national laboratories are developing sensors and data analysis software. The Air Force Technical Applications Center, which has operated a global nuclear event detection system since the first bilateral treaties were signed in the 1960s, is involved, as are the Defense Threat Reduction Agency, the Center for Monitoring Research, and private sector firms. Agarwal's work is being funded by the CTBT Research and Development Program in DOE's Office of Nonproliferation and National Security.

Agarwal has visited many of the agencies, she says, and top managers are willing to clear their calendars and meet with her for an entire day or more. "Everyone involved has been looking for answers to their questions, and one of the things I've been able to contribute already is helping to find out those answers," she says.

Some of the questions to be answered include system-level issues regarding how the communication protocol pieces fit together, how to distribute the data to multiple subscribers so they all receive it simultaneously, and how to ensure that the data is reliable.

The CTBTO is an international organization, and each nation has its own set of data requirements. Some nations, such as the United States, have chosen to receive data from their territory before it is distributed to the rest of the world; some prefer to receive the raw data from some or all of the sensors in the entire network; yet other nations have asked to receive the data from their territory simultaneously with its transmission to Vienna. The communications system needs to allow all of these requirements to be satisfied. Compounding the issue is the requirement that all data must arrive in Vienna within five to 10 seconds of its creation.

For Agarwal, who gave up a job doing off-line programming of assembly line robots for General Motors to earn her Ph.D., an opportunity such as this is one of the reasons she chose to work at a national lab.

"When you go to work for a company, there's a limited scope of what you could be involved in," she says. "At the national labs, you have a lot more opportunity to be involved in a broader space. Working on this project is very exciting."

News Digest


Washington Report

House Science Chair Concerned About SNS Management

House Science Committee Chairman F. James Sensenbrenner, Jr., (R-Wis) has recommended that no construction funds be provided in FY 2000 for the $1.3 billion Spallation Neutron Source. "SNS project management is in turmoil, spending is lagging, project cost and schedule estimates have not been fully developed," he said in a report to Congress last week. "The Department of Energy's complex management approach requires further simplification, and current memorandums of agreement should be substantially strengthened."

Calling the SNS "scientifically meritorious" and saying that its R&D funding "should be continued," Sensenbrenner nonetheless said the project "clearly needs more front-end preparation before it is ready to proceed to full construction."

DOE has proposed a $214-million budget for SNS in FY 2000, $196.1 million of which would pay for construction costs. The remaining $17.9 million would support design and other project activities.

Being constructed at Oak Ridge National Laboratory, the SNS is a collaboration that also involves Berkeley Lab and the national labs at Argonne, Brook-haven and Los Alamos. SNS is scheduled to begin operations in 2005 as the world's largest neutron scattering facility.

In response to Sensenbrenner, Martha Krebs, head of DOE's Office of Science, said that DOE had to change its original cost projections for SNS through a process known as "re-baselining," because Congress took longer than expected to approve the Department's FY99 budget and did not provide all the money that DOE requested.

The re-baselining effort, which Krebs said will not be completed until July, has prevented ORNL from spending as much of the project's FY99 money as initially planned. Obligations and costs for the program have been running at about 60 percent of what was planned under the budget.

Sensenbrenner was critical of Krebs' defense and continued to express skepticism that DOE can complete the SNS on time and on budget. He agreed with Krebs that the appointment of David Moncton as project manager for SNS will help, but he also pointed out that other key SNS positions remain unfilled.

Krebs maintains that DOE officials are committed to working with Congress to resolve any concerns it has about the project.--Lynn Yarris


Berkeley Lab Historical Display at APS

Photo: Berkeley Lab's exhibit at the centennial meeting of the American Physical Society included a poster developed by Ron Kolb of PID and Marilee Bailey of TEID, showcasing seven decades of physics. A record 12,000 physicists attended the APS event, including 45 Nobel Prize winners, Energy Secretary Bill Richardson, and Stephen Hawking (see story below). The Lab exhibit will soon be on display in the cafeteria lobby.


New Deputy Secretary of Energy

T. J. Glauthier has been sworn in as DOE's Deputy Secretary, the number two position in the department.

"T. J. has served the Clinton Administration well and we are grateful to have him here at the Department of Energy," said Energy Secretary Bill Richardson. "His leadership within the Executive Office of the President and private sector experience advising Fortune 500 companies will provide a new perspective to my management team."

Glauthier's duties will entail overall administrative management of the department and direct oversight of the Environmental Quality and Energy Resources business lines. He will also be responsible for DOE's Y2K compliance, will manage environmental cleanup initiatives, and will implement future counterintelligence efforts.

Before coming to DOE, Glauthier was the associate director for Natural Resources, Energy and Science in the Clinton Administration's Office of Management and Budget. He served as the key link between the Administration and the Departments of Energy, Agriculture and Interior, the EPA, NASA, NSF and the Army Corp of Engineers, and a number of smaller agencies. Previously, he directed the energy and climate change sector of the World Wildlife Fund and was involved in the development of the climate change treaty at the Earth Summit in Rio de Janeiro.


Stephen Hawking Endorses Cosmological Constant

By Lynn Yarris

The existence of a cosmological constant counteracting the effects of gravity and causing the universe to expand at an accelerating rate has won the endorsement of Stephen Hawking. At the centennial meeting of the American Physical Society in Atlanta last month, the man widely regarded as the most brilliant theoretical physicist since Albert Einstein recanted his initial skepticism as to the need for this mysterious, self-repelling property of space first proposed by Einstein.

"I have now had more time to consider the observations, and they look quite good," Hawking told reporters at an APS press conference. "This led me to reconsider my theoretical prejudices. I now think it is very reasonable that there should be a cosmological constant."

It was only about a year ago that Hawking, holder of Sir Isaac Newton's chair as Lucasian Professor of Mathematics at Cambridge University, expressed doubts about the observations being reported by the Supernova Cosmology Project and the High-z Supernova Search Team. These observations indicated that not only is the universe expanding, but the rate of expansion is accelerating. Hawking called these observations "preliminary results" and said they were "unnecessary" in light of his own views of cosmic origins.

Hawking now joins Alan Guth of MIT, who originally devised the inflationary theory of the Big Bang, as a believer in the cosmological constant.

He need not be embarrassed for his initial skepticism. Einstein himself once called the cosmological constant "the biggest blunder of my life."

For their supernovae findings, which brought the cosmological constant back to life, the Supernova Cosmology Project and the High-z Supernova Search Team shared Science magazine's "Breakthrough of the Year" award for 1998. Both are international collaborations, with the former based at Berkeley Lab and headed by Saul Perlmutter of the Physics Division and the latter led by Brian Schmidt of Australia's Mount Stromlo and Siding Spring Observatories.

Hawking is among the cosmologists who are suggesting that the cosmological constant is not simply a lucky accident but a necessity for life. The argument goes that there may have been an infinite number of big bangs going off in a larger "multiverse," each with different values for the cosmological constant. Only those values that are compatible with life could be observed by beings such as ourselves.


Maurice Goldhaber Wins Fermi Award

Maurice Goldhaber of Brookhaven National Lab, brother of Berkeley Lab physicist Gerson Goldhaber, was named co-winner of the Enrico Fermi award along with Michael E. Phelps of UCLA' s School of Medicine. The award is granted for a lifetime of outstanding scientific achievement in the field of nuclear energy.

Goldhaber, 87, will receive the award for his contributions in nuclear and particle physics. He was the first to measure accurately the mass of the neutron and later provided key support for the development of the Standard Model.

UC Urges Tax Return Donations for Breast Cancer Program

In an open letter on April 2, UC Vice President of Health Affairs Cornelius L. Hopper appealed to everyone filing income tax returns this month to make a contribution to the Breast Cancer Research Fund, a program administered by the University of California which conducts research into the causes, prevention, detection and cure of breast cancer. To make a donation check Line 52 on the 1998 California Income Tax Return Form 540.

The UC-administered Breast Cancer Research Program (BCRP) was created by the California Legislature in 1993, with two methods for financing the research. BCRP receives revenue from a two-cent-per-pack cigarette tax and from contributions from the state income tax return donation checkoff program.

"We have raised approximately $15 million each year from these two sources, a substantial amount of money for research, the benefits of which are already being realized," Hopper wrote.-- Monica Friedlander



The March 12 issue of Currents ran an obituary on nuclear physicist Jack Peterson, in which his full name and date of death were published incorrectly. Dr. Peterson's full name is Jack Milton Peterson and he passed away on Feb. 21, 1999. We regret any sorrow these errors may have caused to his friends and family.

GLENN SEABORG: A Life Remembered

Two memorial events to say farewell to Berkeley Lab associate director-at-large Glenn Seaborg were held on March 26 and 27. The first memorial gave Berkeley Lab employees a chance to meet with Seaborg family members and offer final respects to one of the Lab's greatest scientists. The second event was a public memorial held on the campus of UC Berkeley. Seaborg died on Feb. 25 at the age of 86.

"Tomorrow the rest of the world will commemorate Glenn's passing; this afternoon, the Laboratory pays tribute to one of its own," said Berkeley Lab Director Charles Shank in his opening remarks at the Lab memorial in the Bldg. 50 auditorium.

His talk followed a short video featuring a montage of Seaborg images which gave the audience a glimpse into the rich scientific history associated with the Nobel laureate and educator who had a hand in the discovery of 10 atomic elements.

The speakers at the memorial included daughter Lynne Seaborg Cobb and son David Seaborg; former Lab Director Dave Shirley; Al Ghiorso and Darleane Hoffman, two of Seaborg's closest collaborators; Rollie Otto, who worked with Seaborg on developing science education curriculums; and Sherrill Whyte, a long-time administrative and editorial assistant to Seaborg.

Lab Copiers Go Default Duplex

On March 23 the default setting on most Lab copiers has been changed to the duplex mode, meaning that copiers will make double-sided copies from single-sided originals unless users choose to select the single-sided mode on the control panel.

This change -- originally scheduled for December -- is part of a larger effort to reduce paper use and save energy and money. Some Lab copiers have already been set for default duplex in recent years, with Canon copiers being switched last month.

To help with the transition, copiers have been labeled as default duplex and include instructions on how to switch to single sided copying.

A description of the duplex copying policy can be found online at BEA/copierchange.html. The website also includes information on improving controls for users of the Cannon 6650 II model.
