| THPOPT024 | MIST - The MESA-Injector Source Two | 2624 |

Funding: Work supported by the German science ministry BMBF through Verbundforschung The new accelerator MESA (Mainz Energy Recovering Superconducting Accelerator) will provide an average CW electron beam current of up to 10 mA. Operating at 1.3 GHz, this corresponds to a bunch charge of 7.7 pC. The new DC photoemission source MIST is optimized for these requirements. A challenge is heating of the photocathode at high laser power. By a suitable mechanical construction and the use of specific materials, the heat can be dissipated during operation. Options for further improvements are discussed. |

| THPOPT007 | High Bunch Charges in the Second Injection Beamline of MESA | 2574 |
|
||
| MESA (Mainz Energy-recovering Superconducting Accelerator) is an accelerator with two laser-driven electron sources (polarized and unpolarized) operating at 100 kV which is under construction at the Johannes Gutenberg University in Mainz. The unpolarized electron source MIST (MESA Injector Source Two) allows to produce high charged electron bunches with charge up to 7.7 pC. This source and a Mott polarimeter will be arranged on the same height above the MESA injector main beamline. A parallel shifting beamline was developed which allows to transport high charged beam from the source MIST to the main MESA beamline. Moreover, the designed beamline allows 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. | ||
