Since 1965, the IEEE
Nuclear and Plasma Sciences Society has sponsored the biennial Particle
Accelerator Conference. PAC2005 has continued this tradition with
a meeting in Knoxville, Tennessee from May 16-20. In addition to
the usual technical sessions and awards, PAC2005 included a celebration
of the World Year of Physics and a special remembrance of the founding
conference in 1965.
A Particle Science and Technology Award has been presented since
1989 at the Particle Accelerator Conference to honor outstanding
contributions to particle accelerator technology. 2005 winners are
Dr. Ronald C. Davidson, Professor of Astrophysical Sciences at Princeton
University and Dr. Tomas Roser, Associate Chair for Accelerators
and Accelerator Division Head at the Collider-Accelerator Department
of Brookhaven National Laboratory.
Dr. Davidson obtained a Ph.D. in 1966 from Princeton University.
He held a research position at Berkeley for two years after which
he served on the faculties of the University of Maryland (1968 –
1978), Massachusetts Institute of Technology (1978-1990) and Princeton
University (since 1991). He served as Director of the MIT Plasma
Fusion Center from 1978 until 1988. From 1991 until 1996 he was
Director of the Princeton Plasma Physics Laboratory. This award
celebrates his contributions to the understanding of intense charged
particle beams, a field in which he has contributed fundamental
papers throughout his career. This work in plasmas and beams is
the subject of four of his books in addition to ~370 publications
and numerous conference contributions. He has supervised 23 students
to their Ph.D.
Dr. Davidson has served the community in many ways including numerous
government panels and the committees of professional societies.
In particular we note his service to the accelerator community as
Chair (2001-2) of the APS Division of Physics of Beams which since
1995 has co-sponsored the Particle Accelerator Conference.
Dr. Davidson is cited “For pioneering contributions to the
theory of charged particle beams with intense self fields, including
fundamental studies of nonlinear dynamics and collective processes.”
Dr. Roser obtained his Ph.D. from ETH, Zurich in 1984. He joined
the Spin Physics Center at the University of Michigan in 1984 and
was appointed an Assistant Professor in 1990. He was involved in
the acceleration on polarized protons at BNL, Indiana University
Cyclotron Facility and UNK in Russia. In 1991 he accepted a position
at the Brookhaven National Laboratory where he was most recently
promoted to Senior Physicist in 1999. He has been involved in the
development and operation of the AGS and RHIC facilities including
high intensity proton, heavy ion and polarized proton operation.
He has documented his work in more than 40 journal papers and more
than 165 conference papers.
Resonance depolarization is a significant barrier to the acceleration
of polarized protons in a high energy synchrotron or storage ring.
The most versatile and powerful technique currently available for
controlling these effects is various forms of the “Siberian
Snake” concept. Dr. Roser has played a leading role in many
implementations and developments of this concept, including ones
in the AGS and RHIC rings as demanded for collisions of high energy
polarized protons at RHIC. He is also recognized for his leadership
role in many other aspects of the polarized proton project.
Dr. Roser is cited “For pioneering scientific work and introduction
of new technology in the acceleration, storage and collision of
polarized protons in the high energy collider RHIC.”
