Perspectives of Plasma-Wakefield Acceleration at DESY
Florian Gruener (DESY)
Seminar Room 3, 14.30h
Accelerator physics experiences the rise of a new field: plasma wakefield acceleration (PWA). The perspectives are right on hand: ultra-high field gradients and intrinsically ultra-short bunches, both of which have been measured in various labs across the world. These findings even allow thinking about high-energy applications. Thus, even CERN now plans a proton-driven PWA project. However, such schemes only work if the relatively long proton-beam undergoes self-modulation on the scale of the plasma period. In order to study this underlying process, we want to launch a pilot-study based on PITZ-electron beams. Theoretical estimates clearly show that plasma inhomogeneities are very crucial. The PITZ-PWA project, embedded in LAOLA, the Laboratory for Laser- and beam-driven Plasma Acceleration (a collaboration of DESY and Hamburg University), will study the feasibility of beam-driven high-energy physics colliders concepts.
