Cryogenic detector and sensor production for rare event searches at the Technical University of Munich — •Elizabeth Mondragon, A. Kinast, A. Langenkaemper, A. Muenster, T. Ortmann, W. Potzel, S.

For rare event searches, such as the direct dark matter search experiment CRESST (Cryogenic Rare Event Search with Superconducting Thermometers), highly sensitive temperature sensors and cryogenic detectors are indispensable. A very low energy threshold (≪ 100 eV) and good energy resolution is required to increase the experimental sensitivity particularly for low mass dark matter particles (mDM < 5 GeV/c2) and to differentiate between these rare events and other particle interactions such as, e.g., radioactive backgrounds. In this contribution we present an overview of the various facilities and techniques available at TUM which are necessary for the production, development and improvement of low temperature detectors and temperature sensors. We also explain the methods we employ for the study and characterization of such technology and the potential applications. In addition, we discuss the quality requirements imposed on the developed systems. This research was supported by the DFG cluster of excellence "Origin and Structure of the Universe", by the BMBF Verbundprojekt 05A2017 - CRESST-XENON and by the SFB1258.
