Dissertation at the Intsitute of Nuclear Physics on the top of DarkMESA

We congratulate Dr. Micro Christmann on the completed dissertation entitled

"Design Studies for the Beam Dump Experiment DarkMESA"

In his PhD thesis Mirco Christmann from the group of Prof. Achim Denig has performed a full scale design study for one of the three experiments under construction for MESA - the DarkMESA experiment. This uses the P2 beam trap as a target for the possible production of light dark matter particles. In the DarkMESA detector, which is well shielded more than 20 meters behind the beam catcher, there is the possibility to detect the dark matter particles by interaction with the electrons in the detector material.

In his work, Mr. Christmann has performed a detailed simulation of the complete experimental environment and thus determined the sensitivity of different configuration levels of DarkMESA. Furthermore, he has studied different detector materials and investigated the detection of low energy electrons in crystals. He has also prepared, performed and evaluated several beam times at MAMI for this purpose.
