| Keith
Symon and Stephen Milton Win Particle Science and Technology Award for 2003 |
| Since
1963, the IEEE Nuclear and Plasma Sciences Society has sponsored the
biannual Particle Accelerator Conference. The 2003 PAC met in Portland,
Oregon from May 12-16. Since 1989, a Particle Science and Technology
Award has been presented at PAC to honor outstanding contributions
to particle accelerator technology. The 2003 winners are Dr. Keith
Symon, Emeritus Professor of Physics at the University of Wisconsin,
Madison and Dr. Stephen Milton, Senior Scientist at Argonne National
Laboratory. Dr. Symon obtained a Ph.D. in 1948 from Harvard University. After that he was on the faculty in the Physics Department of Wayne University, Detroit, MI, from 1947-1955. Then he joined the faculty of the Physics Department of the University of Wisconsin-Madison. In 1990 he was made Emeritus Professor of Physics. At the same time he was a staff member of the Midwestern Universities Research Association (MURA), 1956-67 and then technical director, 1957-60. He was chairman Argonne Accelerator Users Group, 1961-62 and acting director Madison Academic Computing Center, 1982-83 and acting director, UW-Madison Synchrotron Radiation Center, 1983-85. He has been a most productive research physicist working in the areas of the design of particle accelerators and plasma physics. Besides inventing FFAG accelerators he developed the smooth approximation method for approximating the solutions of differential equations with periodically varying coefficients, formalized the theory of radio-frequency acceleration in fixed field accelerators, and contributed, greatly, to the development of colliding beam techniques. He was among the first to develop the theory of collective instabilities in accelerators. (A subject that spawned a thousand papers.) He also contributed to the linearized analysis of inhomogeneous plasma equilibria and developed a method of bit pushing and distribution pushing techniques for the numerical solution of the equations employed in both plasma physics and the study of collective instabilities in accelerators (the Vlasov equation). He was an outstanding supervisor of graduate students, having been the major professor for 20 graduate students gaining Ph.D.s from the UW-Madison. He was author of Mechanics, a popular undergraduate textbook, Addison-Wesley, 1953, 3rd Ed., 1971. Dr. Symon is cited “For many fundamental accelerator concepts which include invention of Fixed Field Alternating Gradient Accelerators (FFAG), most notably incorporated into spiral sector cyclotrons; for defining a formalism describing motion under the influence of RF as required for stacking and other particle manipulations; and for techniques for analyzing collective instabilities.” Dr. Milton obtained a Ph.D. in 1990 from Cornell University. After a post-doctoral position at the Paul Scherrer Institute in Switzerland from 1990-92, he held various positions at Argonne National Laboratory. He currently serves as ANL LCLS Project Director. The Linac Coherent Light Source (LCLS) project will construct an x-ray free-electron laser at the Stanford Linear Accelerator Center (SLAC). At Argonne, Dr. Milton will direct efforts that will create the undulator and associated systems component of the LCLS. As part of the team that built and commissioned the Argonne Advanced Photon Source (APS), Dr. Milton was manager for the Injector Synchroton Ring. He then led the effort to create the Low_Energy Undulator Test Line (LEUTL) and simultaneously was group leader of the APS Accelerator Physics Group. Using the LEUTL facility, a Free Electron Laser employing self-amplified spontaneous emission (SASE) was created. At this facility they first demonstrated lasing to saturation of a visible and ultraviolet SASE FEL. This FEL is now regularly operated and tunable down to 130 nm. Dr. Milton is cited “For contributions to coherent radiation sources especially his leading role in achieving saturated operation at visible and ultraviolet wavelengths in a self-amplified spontaneous emission free-electron laser.” This article was prepared by Bruce Brown, the Chair of the NPSS Particle Accelerator and Technology Committee.
