Laboratory scientists have been named fellows
of the American Physical Society, an honor bestowed on those
recognized by their peers for outstanding contributions to physics.
The honorees are Robert Cauble, James Hammer, Joseph
Nilsen, and Ann Orel Woodin.
Cauble, a senior scientist
in the Laboratory's High-Energy-Density Physics and Astrophysics
Division, was cited for "important contributions to the understanding
of the equation-of-state of dense, strongly coupled plasmas." His
work has included using a laser to shock matter to a million atmospheres
of pressure to learn more about the behavior of hydrogen, laser
fusion, and how stars and planets form and evolve.
Hammer was recognized for
his pioneering work in developing novel approaches to fusion and
high-energy-density plasma applications, including contributions
to the fast igniter inertial confinement fusion (ICF) concept, acceleration
of compact toroidal plasma rings, and the use of z-pinch x-ray sources
Nilsen was cited for his
contributions to the understanding and development of x-ray lasers.
He demonstrated the world's shortest-wavelength, highest-energy
x-ray laser and discovered the prepulse technique used to drive
virtually all x-ray laser systems.
Woodin was honored for "pioneering
the understanding and development of theoretical methods for studying
excitation, ionization, and dissociation of polyatomic molecules."
She divides her time between the Laboratory and the University of
California at Davis, where she is a professor in the Department
of Applied Sciences.
For the second consecutive
year, Bruce Curtis of the Computation Directorate has been
a member of a team receiving a Gordon Bell Prize, the most
prestigious award in high-performance computing. The team comprises
13 members, and it won in the "special" category for its submission,
"High-Performance Reactive Fluid Flow Simulations Using Adaptive
Refinement on Thousands of Processors." The paper describes the
largest and highest-resolution three-dimensional simulation of a
detonation front propagating through stellar material. Curtis says,
"This helps determine how a supernova explodes and aids in the understanding
of the origin and evolution of the
Dave Cooper, Associate Director
for Computation, says of Curtis, "Bruce is a person with almost
unique skills. He is one of just a few people in the world who fully
understand all of the details of a computer as well as how applications
'fit' on them and run." On Curtis's two consecutive wins, Cooper
likens it to "winning back-to-back Oscars!"
