Diagnostics for stable operation of a 200 TW laser system for laser-plasma acceleration — •Spencer Windhorst Jolly1,2,3, Dominik Trosien1,2, Byunghoon Kim1,2,3, Matthias Schnepp1,2, Vincent Leroux1,2,3, and Andreas Richard Maier1,2 — 1CFEL, Center for Free-Electron Laser Science, 22607 Hamburg, Germany — 2University of Hamburg, Institute of Experimental Physics, 22761 Hamburg, Germany — 3ELI Beamlines, 18221 Prague 8, Czech Republic
Laser-plasma based acceleration has matured into a technique providing comparable electron energies and secondary source characteristics to conventional accelerators. The missing piece is stability and repetition rate, which are, among other aspects, severely limited by the driver laser performance. Within the LAOLA Collaboration, the University of Hamburg and DESY work closely together to combine university research in the field of laser-plasma acceleration with the expertise of a large and well-established accelerator facility. We present in this talk a summary of hardware, software, and operation based changes to the 200 TW laser system (ANGUS) to increase ease of operation and stability. We concentrate on camera-based alignment and diagnostics, implemented within the DESY accelerator controls system. These improvements to the laser system will greatly help the operation of LUX and REGAE, the two dedicated experiments in Hamburg which study laser-plasma acceleration.
