Beam dynamics simulation of the high bunch charge in the second injection beamline of MESA — •Anatolii Kalamaiko¹, Kurt Aulenbacher^{1, 2, 3}, Monika Dehn¹, and Simon Friederich¹ — ¹Institute of Nuclear Physics, Mainz, Germany — ²Helmholtz Institute Mainz, Germany — ³GSI Helmholtzzentrum fur Schwerionenforschung, Darmstadt, Germany

MESA (Mainz Energy-recovering Superconducting Accelerator) is an electron accelerator with the beam energy up to 155 MeV, which is under construction at the Johannes Gutenberg University in Mainz. The accelerator has two laser-driven 100 KeV electron sources (polarized and unpolarized). The unpolarized electron source MIST (MESA Injector Source Two) allows producing highly charged electron bunches (up to 7.7 pC in a bunch). This electron source will be arranged above the main injector beamline of MESA. A special parallel shifting beamline was developed for transporting and compress with a buncher of electron beam from the electron source MIST to the main MESA beamline. This report presents the last results of the beam dynamics simulation and status of the second separation beamline of MESA.
