Cameron Geddes Lawrence Berkely National Laboratory

Cameron Geddes is a physicist in the LOASIS program of Lawrence Berkeley National Laboratory. He received his Ph.D. in 2005 at the University of California, Berkeley. He is PI on ATLAS and NERSC simulation grants totaling more than five million CPU hours for large scale modeling of laser driven accelerators, and also pursues experiments on laser guiding and control of particle injection in laser accelerators, as well as on proton acceleration and x-ray production. Dr. Geddes received the 2006 American Physical Society Rosenbluth dissertation award in plasma physics and the 2005 Hertz foundation dissertation prize, as well as an LBNL Outstanding Performance, award for his Ph.D work demonstrating the plasma channel guided laser wakefield accelerator, in which laser pulse propagation was controlled by a pre-formed plasma channel resulting in production of monoenergetic beams for the first time in such an accelerator. Previous work includes Langmuir wave decay experiments in the Nova laser plasma physics group at Lawrence Livermore National Laboratory, ion wave mixing experiments at the Omega laser (Polymath research), small aspect Tokamaks (Princeton/U. of Wisconsin), and nonlinear optics (Swarthmore). He received the American Physical Society Apker award for the outstanding undergraduate thesis, and the Swarthmore College Ellmore prize for outstanding work in physics (1997) for research on the equilibria of spheromak plasmas.
