High bunch charges in the second injection beamline of MESA — •Anatolii Kalamaiko, Kurt Aulenbacher, Monika Dehn, and Simon Friederich — Institut für Kernphysik, Universität Mainz, Germany

MESA (Mainz Energy-recovering Superconducting Accelerator) is an accelerator with two laser-driven electron sources operating at 100 kV which is under construction at the Johannes Gutenberg University in Mainz. One of the sources is the unpolarized electron source MIST (MESA Injector Source Two) producing a bunch charge of up to 7.7 pC. This source and a Mott polarimeter will be arranged on the same height above the MESA injector main beamline. Thus, it is necessary to develop a parallel shifting beamline to transport electron beam from the source MIST to the main MESA beamline. Besides, the designed beamline should allow to transport beam from the electron source STEAM to the Mott polarimeter. This report is dedicated to the design of the separation beamline which transports and compresses highly charged electron bunches from the electron source MIST to the first acceleration section of MESA.
