Prof. James B. Rosenzweig

Prof. James Rosenzweig is the Director of PBPL. His research interests encompass a wide variety of topics in experimental and theoretical aspects particle beam, plasma and radiation physics. These topics are all linked in that they are ultra-fast, high energy-density phenomena. As it is a critical underpinning of the most compelling fields driving beam physics, he is particulary active in the area of ultra-high brightness electron beam generation, a hybrid field drawing from beam physics, plasma physics, and an assortment of intricate technologies. The generation, violent acceleration, and diagnosis of these beams, which consist of essentially picosecond-long pulses of ultra-relativistic single component plasma, enables research in a host of other subjects of interestÑ specifically, advanced accelerators and free-electron lasers/scattering sources.

The subjects under active investigation in Prof. Rosenzweig's group include free-electron lasers, inverse Compton scattering sources, plasma wake-field acceleration and injection, nonlinear plasma phenomena, optical acceleration advanced microwave devices, ultra-strong magnetic elements, and. While some of his research is conducted at collaborating laboratories, such as Brookhaven, SLAC, Livermore, Fermilab, and INFN-LNF, most of the group's efforts are centered at two on-campus laboratories. The UCLA facilities consist of the Neptune laboratory, a state-of-the-art advanced accelerator laboratory, and the PEGASUS laboratory, which is dedicated to the study of free-electron lasers and related physics.

Prof. Rosenzweig obtained his Ph.D at the University of Wisconsin - Madison, in 1988. Upon graduation, he held an assistant physicist appointment at Argonne, and from 1989 to 2000 was Robert R. Wilson Fellow in Accelerator Physics at Fermilab. He joined the UCLA Dept. of Physics faculty as an assistant professor in 1991. Since 1999, he has been Professor of Physics at UCLA. He has had visiting physicist positions at Argonne National Laboratory, and Fermilab. On sabbatical in 2003, he was Visiting Professor, Universita di Roma "La Sapienza", and visiting scientist at Laboratori Nazionale di Frascati (INFN-LNF). He is a frequent lecturer in the US Particle Accelerator School.

Prof. Rosenzweig has received a Sloan Fellowship, an SSC Junior Faculty Fellowship, and has been selected as a Fellow of the American Physical Society. He is author, or co-author, of nearly 200 scientific publications. He is active in APS committees, as a proposal and journal referee, and as an organizer of topical and major conferences. Prof. Rosenzweig has developed a course on modern approaches to beam physics, Physics 150 "The Physics of Charged Particle and Beam Physics", which is traditionally taught in the spring quarter yearly. He has written a textbook for the course, which has been published by Oxford University Press in 2003, "Fundamentals of Beam Physics".

James Rosenzweig was born in Denver, CO, in 1960, and was raised in Milwaukee, Wisconsin and in London, England. He is married and has three children. He partakes in numerous outdoor sports, and is an avid bicycler. His interests include music, study of language and history, the enjoyment of the wines of the world, and the Green Bay Packers.
