Scientists have declared that the top quark, the last of the six quarks predicted by the Standard Model of particle physics and one of the fundamental building blocks of matter, has been discovered. Both of the main experimental groups at Fermilab's Tevatron collider--the Collider Detector Facility (CDF) and the D-Zero (D0) group--have independently observed the production and decay of what for nearly two decades had been the crucial missing piece in the scientific picture of matter.
"This is one of the ten most important accomplishments in this century in this field," said Tom Trippe, a physicist in LBL's Physics Division (PD) and a member of the D0 group, in a story reported in the March 1 San Francisco Chronicle.
"We were quite confident we had it last April but we were being conservative in our claims," said Lina Galtieri, a PD physicist who leads LBL participation in the CDF group, which announced the first evidence of the top quark last April (see Currents, April 29, 1994 ). At that time, the CDF group said it had a strong case for the top quark but lacked enough data to claim discovery.
Since then, the CDF and D0 groups have tripled the amount of data collected. Details of the experiments were presented during a March 2 symposium at Fermilab and papers have been submitted to Physical Review Letters. The top quark is reported to have about the same mass as an atom of gold, or about 200 times the mass of a proton, making it by far the heaviest elementary particle ever observed.
Top quarks exist only for an instant before decaying into a bottom quark and a W boson, which means those created at the birth of the universe are long gone. Even the Tevatron, the most powerful collider in the world, has difficulty creating top quarks. It is estimated that one pair of top quarks is produced for every 10 billion proton-antiproton collisions. According to the Standard Model, however, the existence of the top quark at creation was necessary along with the other five types of quarks. The only types that have since survived in nature are the up and the down quarks, the pair that make up the protons and neutrons in the nuclei of all the known atoms in the universe.
Nearly a thousand scientists from around the world took part in the CDF and the D0 experiments; LBL researchers made vital contributions to both collaborations. Physicists and engineers at LBL designed a sophisticated microchip for the Silicon Vertex Detector, an extremely high-resolution instrument at the heart of the CDF detector system that enabled precise identification and tracking of bottom quarks, one of the top quark's signature decay products. The CDF's Hadronic End Calorimeter was also built at LBL.
The D0 group at LBL, which is led by Ron Madaras, was responsible for designing, building, testing, and commissioning two critical components of the D0 detector array: the Electromagnetic End Calorimeter, which identifies and measures the energies of electrons; and the Vertex Detector, which detects the tracks left by charged particles.
Later this month, the CDF & D0 groups at LBL will present seminars on their findings.
George Smoot, who discovered the ancient seeds that grew into the galaxies and superclusters of galaxies that populate today's universe, has been named one of eight winners of the 1994 E.O. Lawrence Award by Secretary of Energy Hazel O'Leary.
Smoot, an astrophysicist in LBL's Physics Division and professor of physics at UC Berkeley, is the 23rd LBL recipient of the award. Inaugurated in 1959, the Lawrence Award honors the memory of LBL founder Ernest Orlando Lawrence. It includes a gold medal and $10,000.
"Because Lawrence was a remarkable experimental physicist, this is a particularly great honor," Smoot said of the award. "This work would not have been possible without the tradition of excellence established by Lawrence, the support of the lab leadership, and in particular, Bob Cahn (Physics Division Director).
Smoot won in the category of physics for his work on the cosmic microwave background, the faint afterglow left over from the Big Bang. He was cited "for his leadership in the remarkably accurate measurements of the variations in the cosmic microwave background radiation, thus clarifying our understanding of the early history of the universe, the distribution of dark matter, and the formation of stars and galaxies."
The cosmic background radiation was first detected in 1964 by Nobel Prize winners Arno Penzias and Robert Wilson. While doing satellite communications experiments, the pair encountered interference, a hiss that was remarkably uniform no matter which direction in the sky their antenna was pointed. This microwave noise--which had a temperature of 2.7 degrees kelvin--turned out to be the relic radiant heat from the primeval fireball.
From that date, researchers began looking for tiny fluctuations in this radiation. If these irregularities existed, then over the billions of years since the Big Bang, gravity would have magnified them into the stars and galaxies we observe today. If they did not exist, then the Big Bang theory of the origin of our universe was off base.
In 1976, Smoot was a key member of the team that discovered what was called "the dipole anisotropy" of the cosmic microwave background. This established that the Milky Way is not only expanding along with the rest of the universe, but, surprisingly, is moving at its own peculiar velocity at more than a million miles per hour.
According to the Lawrence Award citation, "Knowledge of this velocity has allowed cosmologists to make one of the best estimates of the mass density of the universe. This estimate makes a very strong case for the existence of more matter in the universe than can be accounted for by ordinary matter, helping to make the case for unusual forms of dark matter."
Two years earlier, Smoot had submitted a satellite proposal to NASA to measure and map the cosmic microwave background. The satellite was launched in 1989, and in April 1992, Smoot's team announced they had found what had evaded scientists for 28 years.
The team displayed images that mapped the unevenness in the microwave sky. The sky maps record a time about 300,000 years after the Big Bang, the earliest pictures we have of the universe. They show regions that vary in temperature and density by one part in 100,000. These irregular regions represent the seeds of creation.
Since then, the findings have been confirmed by several groups including a December 1992 confirmation by an MIT and Goddard Space Flight Center experimental team.
Smoot, whose quest consumed 20 years, was born in Florida in 1945. He attended MIT, earning a bachelor's degree in mathematics and physics and a doctorate in physics. In 1971, he came to LBL, joining the team of Nobel Prize winner Luis Alvarez, and began a career in cosmology.
Other winners of 1994 Lawrence Awards are Michael Campbell and John Lindl from Lawrence Livermore National Laboratory (National Security); Gregory Kubas from Los Alamos National Laboratory (Chemistry); Edward Larsen from the University of Michigan (Nuclear Technology); Gerald Ludtka from Oak Ridge National Laboratory (Materials Research); John Till from Radiological Assessments Corp. (Environmental Science and Technology); and John Boice from the National Cancer Institute (Life Sciences). The awards will be presented in Washington, D.C., at a date to be announced.
Energy Secretary O'Leary said of the recipients, "The results of these winners' work clearly demonstrate the contributions that basic and applied research make to our Nation, to our economy, to our health and safety, and to our understanding of the universe around us."
The Office of Naval Research (ONR) has selected LBL to create and host one of two Molecular Design Institutes, an initiative spearheaded by Mark Alper and colleagues in the Materials Sciences Division. The Laboratory has been awarded an initial grant of $735,000 and is scheduled to receive an additional $6 million later this year. Georgia Tech was selected as the other host, for which it will receive $490,000 and $4 million, respectively.
The purpose of the Molecular Design Institute (MDI) is to combine the efforts of chemists, biochemists, and physicists for the atomic-scale design, synthesis, processing, and characterization of new molecules and materials. Potential areas of application include electronics, photonics, sensors, catalysts, and a wide variety of novel materials and coatings.
LBL will establish its MDI in collaboration with five universities and four private companies, which, with the Laboratory, formed a consortium and put together an MDI proposal for the ONR grant. The other members of the consortium include UC Berkeley, UCLA, Cal-Tech, Penn State, Rice University, IBM Almaden, AT&T Bell Labs, Motorola, and Intel.
In a released statement announcing the grants, ONR said, "The intention of these awards (to LBL and Georgia Tech) is to exploit recent advances in the atomic and molecular level of understanding materials synthesis and processing in order to develop superior approaches to new material structures."
Paul Alivisatos, a chemist with LBL's Materials Science Division and professor in UCB's Chemistry Department, has been named scientific director of the new institute.
Intensive debate is taking place in Washington, D.C., about how to reform the Department of Energy and how to cut its budget. For the moment, however, says LBL Director Charles Shank, the Laboratory's total budget for next year looks as though it will be roughly the same as it is currently.
Updating employees during a February 23 town meeting, Shank said the changes under discussion are so vast and so volatile that no one can know the outcome. Although there is great uncertainty, Shank said there are also specific opportunities from which LBL could benefit.
The Clinton Administration has submitted its budget proposal to Congress. It calls for a $219.1 million total DOE budget for LBL for the 1996 fiscal year as compared to $227 million for the current year. The operating budget--which excludes construction funds, such as money for the Human Genome Laboratory in 1995--is $182 million in both 1995 and 1996.
DOE has proposed a "Scientific Facilities Initiative" that would increase funding for a number of major user facilities by $100 million. Shank said Congress appears to be receptive to the initiative.
Testifying last week before the House Science Committee's Subcommittee on Energy and Environment, Shank said he and other national laboratory directors made the case for the initiative. The federal government has invested billions in building these facilities but due to a dearth of operating funds, is not able to use them full time.
"We are now operating the Advanced Light Source (ALS) at only 56 percent of its potential," Shank said. "Likewise the 88-Inch Cyclotron and the National Center for Electron Microscopy (NCEM) are not able to accommodate all those in line to use them. Increasing the operating budget of DOE scientific facilities should be a priority."
Under the initiative, the ALS' FY96 budget would be $29.9 million, an increase of $8.7 million. NCEM's budget would jump to $3.6 million, an increase of $1 million, and the 88-Inch Cyclotron's budget would climb to $10.4 million, up $1.7 million.
Subcommittee Chairman Rep. Dana Rohrabacher (R-Calif.) wants to cut $1 billion from the combined FY96 budget requests of DOE, EPA, and the National Oceanic and Atmospheric Administration. Questioning Martha Krebs, the head of DOE's Office of Energy Research, Rohrabacher asked her to list her budget priorities. Krebs testified that the Scientific Facilities Initiative was a major priority.
While some programs could see increases, Shank said Congress is intent on cutting overall spending. Within DOE, fusion programs are under heavy attack. Other programs that could be cut include environmental restoration programs and energy efficiency programs.
Concurrent with the changes being discussed by Congress, DOE itself is attempting to restructure the department. Shank is one of three national laboratory directors who serve on the steering committee of the DOE restructuring effort, and will be in Washington working on this project in the coming week.
Terming this an opportunity, Shank said DOE's Galvin Report could provide a blueprint for making DOE less bureaucratic and more efficient. Because Congress wants immediate action, Shank said it is possible that DOE may announce changes to the organization as early as May. More dramatic reengineering would come later. n
Nitschke was born in Berlin, Germany, on the eve of World War II. His father fought with the Resistance movement against Adolph Hitler, and was tried and executed by the Nazis when his son was six years old.
Nitschke first came to LBL (then Lawrence Radiation Laboratory) in 1966 as a graduate student on a fellowship from the German government. Working with Earl Hyde, he studied the decay schemes of radioactive nuclei and discovered several new nuclides.
He then began work on the HILAC (Heavy Ion Linear Accelerator) with Al Ghiorso. There he designed a new type of on-line mass spectrometer; this work later became the basis for a thesis when he returned to Germany to complete his doctorate at the Technische Hochschule in Braunschweig.
He spent two years at the Centre National de la Recherche Scientifique in Orsay, France, then returned to LBL in 1971 to assist in the modification of the HILAC into the SuperHILAC. With the accelerator completed, he began to explore its use for experimental purposes. He was a member of the research team that discovered isotope 263106 in 1974.
Nitschke led a distinguished research effort during the 1980s with OASIS (On-line Apparatus for SuperHILAC Isotope Separation), an on-line mass separator. He then devised a Total Absorption Spectrometer (TAS) to measure decay energies and thus define masses. After the decommissioning of the SuperHILAC in 1991, TAS was moved to the UNILAC at GSI in Germany, where the work will be continued by his collaborators.
In 1989, Nitschke developed a concept for the construction of a combination of accelerators that would be able to accelerate radioactive beams with high intensities, and address important problems in astrophysics and nuclear physics. His concept, christened ISL for IsoSpin Laboratory, was recently recommended for inclusion in the 10-year plan being developed by the national Nuclear Science Advisory Council (NSAC).
Nitschke was a significant contributor to the NSD's Low Energy Program. He was a gifted teacher who often participated in mentoring programs. In 1992, he was honored for his substantial contributions to nuclear physics by election to Fellowship in the American Physical Society.
In addition to his career in nuclear science, Nitschke was an exceptional athlete. He competed on the West German rowing team in the 1964 Tokyo Olympics, and was an expert board sailor. He was also an accomplished pianist and opera singer.
Nitschke was a benefactor of many environmental and educational organizations, among them Sierra Club, Cousteau Society, Krishnamurti Foundation of America, and California Academy of Sciences. A scholarship fund for college-level students is being established in his memory. Details will be announced at a later date.
Rhea's involvement with LBL's In-House Energy Management section and the Maintenance and Operations group to implement energy efficiency projects dated back to 1987. According to IHEM's Geoffrey Bell, Rheas' work resulted in significant energy savings for LBL. "The Laboratory owes Michael our gratitude and appreciation for all of the insightful, studious, and thoroughly professional services rendered over past years," Bell said. "Everyone who knew Michael well agrees that it was always a pleasure to work with him."
A college savings fund is being established for Rhea's son David. If you are interested in helping, please make your check payable to Lori Rhea and forward it to Geoffrey Bell, M.S. B90G, before Friday, March 17. Call X4626 for more information.
The University of California was generally favorable in its preliminary response to the recommendations of the Galvin Report, noting that several are already embodied in the current UC-DOE laboratory management contract. In a letter to Secretary of Energy Hazel O'Leary, UC President Jack Peltason said, "We believe implementation of many of the recommendations would further strengthen the effective partnership between the University and the Department of Energy in managing the Lawrence Berkeley Laboratory, Lawrence Livermore National Laboratory and Los Alamos National Laboratory." Peltason did urge, however, that subsequent examinations of laboratory "governance options" include "a specific review of the merits of maintaining strong laboratory-university linkages and of the unique contributions that not-for-profit contractors make to the national laboratory complex."
NEWSWEEK LOOKS AT THE INTERNET:
The February 27 issue of Newsweek was devoted to taking a long hard look at the current state of the computer age. Under the title "Technomania: The Hype and the Hope," the issue explored the impacts on American society of new developments in the so-called information revolution. LBL's own Van Jacobson was featured in a photo with Steve Deering of the Xerox Palo Alto Research Center as co-inventor of the Multicast Backbone or "MBone"--software that efficiently routes videoconferences over the Internet (see Currents, Dec. 9, 1994). Former LBL computer-sleuth Cliff Stoll was the author of another article in the issue entitled "The Internet? Bah!" in which he argued that cyberspace is not and never will be nirvana. In response to the notion that electronic publishing will soon replace books, Stoll wrote, "You can't tote your laptop to the beach."
AAAS ELECTS NEW HEAD; SCIENCE GETS NEW EDITOR:
The American Association for the Advancement of Science, the world's largest general scientific organization, has elected as its next president Jane Lubchenco, a MacArthur Fellow and Distinguished Professor of Zoology at Oregon State University. She succeeds UC Irvine's Francisco Ayala who has become the new chairman of the AAAS board of directors. Lubchenco is the eighth woman to be elected president of AAAS. The organization has also named a new editor-in-chief of its magazine, Science. The selection of Dr. Floyd Bloom, a neurologist with the Scripps Research Institute in La Jolla, Calif., caps a year-long search following the retirement of former editor Daniel Koshland Jr.
The February 10th edition of Science features a report by Nancy Boudreau, Carolyn J. Sympson, and Mina Bissell of the Life Sciences Division, with Zena Werb of UCSF, entitled "Suppression of ICE and Apoptosis in Mammary Epithelial Cells by Extracellular Matrix." It appears that cells have to make a choice between differentiation, growth and apoptosis (programmed cell death) in order for normal tissues to function properly. When this decision making becomes aberrant, the cells could become cancerous. The article describes how extracellular matrix (the mass of fibrous and globular proteins that surround the cell) or ECM, and specifically laminin, an important component of ECM, suppress apoptosis of breast cells in tissue culture and in vivo. The breast cells in transgenic mice that were designed with the capacity to destroy ECM in vivo began to die. It appears that ECM regulates the activity and the level of a "death" gene referred to as ICE. The researchers showed that ECM is an important regulator of tissue-specific genes. These new results establish ECM as a central switch for life/death/cancer decisions. A second article on the subject, "From Laminin to Lamin: Regulation of Tissue-specific Gene Expression by ECM, written by Boudreau, Connie Myers and Bissell, appears in the January 1995 issue of Trends in Cell Biology.
Lowell High School of San Francisco won LBL's fifth annual Regional Science Bowl in a close contest here last Saturday. The team will now go on to the national competition.
The Lowell team beat last year's winner, Homestead High of Cupertino. Third place went to Casa Grande of Petaluma, and fourth to St. Vincente's, also of Petaluma. Science and math whizzes from 12 other Bay Area high schools participated in the annual event.
Sponsored by DOE, Saturday's competition at LBL was one of 44 regional bowls taking place all across the country. LBL scientists, students, and administrative staff, as well as staff from DOE Oakland, participated in the event.
The Bay Area winner--Lowell--now travels to Washington, D.C., to take part in the National Science Bowl, which is co-sponsored by DOE and the Cray Research Foundation.
The regional winner two years ago--Albany High School--went on to take the top prize in the national championships. Last year, the regional winner was Homestead High of Cupertino; the national champion was Westminster School of Atlanta, Georgia.
The format of the Science Bowl is similar to that of the college bowls popular on television in the 1960s. Four-member teams take turns meeting head-to-head in a series of question-and-answer sessions. Questions are taken from a variety of subject areas including astronomy, biology, earth sciences, physics, chemistry, mathematics and computer sciences.
High schools competing this year were: Andrew P Hill (San Jose); Bridgemont (San Francisco); Casa Grande (Petaluma); De Anza (Richmond); Encinal (Alameda); Homestead (Cupertino); Lowell (San Francisco); Miramonte (Orinda); North Marin (Novato); Oakland High (Oakland); St. Ignatius (San Francisco); St. Joseph (Alameda); St. Mary's (Berkeley); St. Vincent (Petaluma); Terra Linda (San Rafael); and Urban School (San Francisco).
The advisory committee represents staff throughout the University system; Vinson is the lab representative. The committee has been asked to comment on selection criteria set by the Board of Regents, suggest leadership qualities required for the position, and suggest any candidates who would be appropriate for the position.
Vinson invites all lab employees to forward their comments to her by March 3, preferably by e-mail at [email protected] You also may reach her by phone at 987-9064 or by fax at 839-3831. She also welcomes comments and candidate suggestions beyond the preferred March 3 date; for maximum effect, however, she should receive comments on criteria by then.
On March 6, the group will meet with the UC Regents search committee. The full Board will act on any proposed revisions to the criteria at its March 16-17 business meeting in Los Angeles.
Scientists and staff versed in the intricacies of environmental engineering received engineering training of a more social nature recently.
In February, 15 Environment, Health and Safety Division managers honed their presentation skills at the first of two workshops designed to improve LBL's communication with the public on such issues as environmental clean-up and general risks from Laboratory operations. The first workshop focused on holding effective public meetings.
EH&S managers are often on the front lines in emergencies at LBL because of their responsibility for Lab safety. "It was my concern for my people to be prepared to deal with both unanticipated and planned contact with the press and the public," said EH&S Division Director David McGraw. "With the training, we'll be better prepared to talk with the community."
The workshop covered all aspects of effective public communication: the importance of having a dry run (practice session), when and when not to use visuals such as viewgraphs, and how to follow up with the community after a meeting.
In role-playing sessions, groups took on hypothetical emergencies at Lab sites such as the National Tritium Labeling Facility and the Hazardous Waste Handling Facility.
Participants were also put in front of the video camera for short impromptu speeches, which were reviewed and critiqued. "The exercises are a good chance for the managers to see how they come across when presenting technical material," said McGraw.
The workshops are an extension of the Environmental Restoration Program Community Relations Plan, a report drafted in preparation for the new Hazardous Waste Handling Facility. The report sets guidelines for public participation in the Lab's management of hazardous waste. Environmental specialists from ICF Kaiser Engineers, who helped draft the communications plan, are also organizing the workshops.
"People are recognizing that interfacing with the public is more and more important," said ICF Kaiser's Polly Quick. "They are discovering that there is not one best way to communicate. Every environmental project is different, and every community is different."
EH&S managers will attend a second workshop in April on communicating effectively with the media.
If you are interested in receiving communications training for your staff, contact Shaun Fennessey at X5122.
