Plasma Wakefield Accelerator Experiments and their Diagnostics

Abstract: Plasma-based particle accelerators have made remarkable progress over the last few years. In particular, the particle-beam-driven plasma wakefield accelerator (PWFA) experiments at SLAC have demonstrated the acceleration of positrons in plasmas, the first energy gain larger than 1 GeV in any plasma-based accelerator, and the energy doubling of 42 GeV incoming electrons over only 85 cm of plasma. The PWFA is one of the schemes that could one day revolutionize particle accelerators, greatly diminishing their size and cost because of it extremely high accelerating gradient (>10 GV/m). Understanding the transverse and longitudinal dynamics of electron and positron beams in long, dense plasmas is therefore key to develop the scheme to the level of a credible technology. A summary of relevant results obtained mainly at SLAC will be presented with an emphasis on the diagnostics that were developed to understand the PWFA. This work is supported by US DoE

Speaker Bio: Patric Muggli graduated in plasma physics from the physics departments of the Swiss Federal institute of Technology in Lausanne. He received his PhD from the same school after studying high power microwave sources. He then joined UCLA as a post-doctoral fellow. He is currently a research professor at the University of Southern California, and leads the laser plasma accelerator group. His main research interest is the plasma wakefield accelerator, which is a beam-driven, plasma-based accelerator. He is a lead experimentalist on the PWFA experiments at SLAC and Brookhaven National Laboratory. He is a fellow of the American Physical Society, and a Nuclear and Plasma Science Society Distinguished Lecturer.
