Light Dark Matter Searches at DarkMESA — •Maik Biroth for the MAGIX collaboration — Institute of Nuclear Physics, Johannes Gutenberg University, Mainz, Germany

The DarkMESA beam dump experiment will search for light dark matter particles. It will be placed behind the P2 experiment at the future MESA electron accelerator, where an unprecedented amount of electrons-on-target can result in the radiative production of dark photons. In various models, such a dark photon decays predominantly into a pair of dark matter particles in the sub-GeV range. These will be detected by a sophisticated setup based on a solid and reliable detection technology.

In this talk, the development status of the detector system and the estimated exclusion limits will be presented.
