Description

In a recent report, by the P5 subpanel (1) the development of new technologies that will enable future e+e- colliders to be both more compact (high gradient) and cheaper (high efficiency) than colliders based on existing RF technology has been given a high priority. Plasma Wakefield Accelerator (PWFA) is one concept that is being aggressively pursued with this goal in mind. Most of the PWFA research is being carried out by the E200 collaboration on the FACET facility at SLAC. The physics of an electron beam-driven wake and by a positron beam-driven wake in plasma is qualitatively different. I will describe the richness of this interaction and present the latest results on the accelerated beam parameters that have been obtained using both the electron and positron bunches to excite wakes in meter-scale plasmas.
