Four Livermore National Laboratory scientists, including one from Pleasanton, have been selected as 2016 fellows of the American Physical Society.
They were recognized for their exceptional contributions to the field of physics through research, leadership, applications of physics or contributions to physics education. APS fellowship is considered a distinct honor because members are nominated and elected by their peers.
The APS' division of Plasma Physics recognized physicist Hui Chen of Pleasanton for her "pioneering experimental research on relativistic positron generation using ultra-intense short-pulse lasers."
Chen joined LLNL in 1999 after completing her Ph.D in plasma physics at Imperial College in London. She also holds a bachelor's degree in physics at Chengdu University of Science and Technology in China.
She has been active in several lines of plasma physics research at the Livermore Lab, including laser-produced matter/antimatter plasmas, X-ray spectroscopy of highly charged ions, innovative instrumentation and fundamental short-pulse laser-plasma physics.
The work cited for the APS fellowship was her trailblazing decade-long experimental study of laser-produced relativistic electron-positron plasma "jets," using five larger laser facilities on three continents.
Also honored were physicist Adam Bernstein, chief scientist Omar Hurricane and physics division leader James Trebes.
Bernstein was cited by the Division of Nuclear Physics for "pioneering work at the intersection of nuclear science and nuclear nonproliferation, including the development of antineutrino-based methods for monitoring the production of fissile material and large volume detectors for rapid screening of cargo for the presence of fissile material."
He joined LLNL as a staff physicist in 2002 and now leads the Rare Event Detection Group. His research interests include the development of improved radiation detection techniques that facilitate global nuclear arms and materials control, nonproliferation and disarmament.
He received his bachelor's degree in physics from UC Berkeley and D. in experimental high energy physics from Columbia University.
Hurricane is the chief scientist of the Lab's ICF Program and lead of Integrated Experiments. He was cited by the APS division of Plasma Physics for "visionary leadership in experiments on the National Ignition Facility (NIF) laser and innovative work in understanding instabilities in high energy density.
He joined the Lab after completing graduate and postdoc studies in plasma stability theory at UCLA.
Trebes, the Physical and Life Sciences division leader, was recognized for his "contributions in laser physics and the application of physics to other disciplines, for leadership in multiple national security areas, and for contributions to education in the sciences and engineering."
He joined the Laboratory in 1984 and has worked in a broad range of research and development areas including X-ray lasers, ICF, weapons physics, X-ray optics, detectors, nonproliferation projects in Russian and Libya, military special operations technology, medical technology, bio-detection, enhanced surveillance and space technology.
He received his bachelor's degree in physics from Georgia Tech and his Ph.D. D in physics from Yale University.
