Four Laboratory physicists have been named fellows of the American Physical Society (APS): Peter Beiersdorfer and Karl van Bibber of the Physics and Advanced Technologies (PAT) Directorate, David Munro of the Defense and Nuclear Technologies (DNT) Directorate, and Seigfried Glenser of the National Ignition Facility (NIF) Programs Directorate.
Beiersdorfer, leader of PAT’s Atomic Spectroscopy Group, was cited for his “many contributions to precision
X-ray spectroscopy of highly charged systems and application of this spectroscopy to plasma and astrophysical problems.” He joined the Laboratory in 1988, earned his B.S. and M.S. in physics from Auburn University and an M.S. and Ph.D. in plasma physics from Princeton University.
Van Bibber, chief scientist in PAT, was elected for his “leadership role in an ultra-sensitive search for dark-matter axions, and the conception of other elegant experiments for detection of the axion.” Van Bibber, who received his bachelor’s and doctorate at the Massachusetts Institute of Technology, came to Livermore in 1985 from Stanford University, where he had been an assistant professor of physics. He started the Laboratory’s High-Energy Physics and Accelerator Technology Group in 1991 and was Livermore’s project leader for the construction of the B Factory at the Stanford Linear Accelerator Center (SLAC), a collaboration of SLAC and Lawrence Berkeley and Lawrence Livermore national laboratories.
Munro, a Laboratory employee for 21 years, is a physicist involved in laser fusion target design. He was singled out for “seminal contributions to the design of laser-driven Rayleigh–Taylor experiments, and to the analysis and design of shock-timing experiments for cryogenic inertial confinement fusion targets.” He earned his Ph.D. at the Massachusetts Institute of Technology in 1980 and has focused on laser fusion throughout his career. Until a few years ago, he was mostly involved in designing experiments on the Nova laser. Currently, he is designing targets for NIF.

Glenser, an experimental physicist, was cited for “the development of Thomson Scattering for the diagnostics of high-temperature inertial confinement fusion plasmas and for important contributions to understanding of plasma waves, atomic physics, and hydrodynamics of hot dense plasmas.” Currently a group leader for Plasma Physics in NIF’s Inertial Confinement Fusion program, he earned his undergraduate degree and Ph.D. at Ruhr-Universität Bochum in Germany. He has been in the U.S. since 1994, when he first joined Livermore as a postdoctoral fellow.

In late 2001, Livermore’s Clinton M. Logan was made a fellow of the American Society of Mechanical Engineers in recognition of his outstanding engineering achievements. A graduate of the University of California at Davis (M.S., 1972), Logan performed the structural design for the first vacuum line-of-sight employed in underground tests of nuclear explosives. Later, he designed and patented a rotating vacuum seal that became an enabling technology for an international radiation effects program at the rotating Target Neutron Source II. As the leader of the Material Characterization Group for Livermore’s X-Ray Laser program, Logan stretched film radiography to unprecedented accuracy. Recently, he has been an innovator in developing digital (filmless) mammography and in applying flat-panel electronic x-ray imagery to nondestructive evaluation.

Recently, Tim Andrews, Mark Mintz, and Bill Blevins, employees of Livermore’s Tritium Facility, received Pollution Prevention Awards from the Department of Energy–National Nuclear Security Administration Oakland Operations Office. The awards honor their efforts in tritium recycling in support of the U.S. Army Industrial Operations Command project to recover and reuse tritium from military field devices. The project involves disassembling the equipment and segregating tritium-containing ampules from nonradioactive components. The Livermore tritium specialists release the tritium from the ampules, capture it, and accumulate the captured tritium in specialized shipping containers. These containers are sent to the Tritium Facility at DOE’s Savannah River Site, where the tritium is reused. During fiscal year 2001, this waste minimization project recovered an estimated 27,000 curies of tritium, avoiding approximately 16,000 kilograms of radioactive waste.
