Optimization of Cryogenic Light Detectors for the CRESST Experiment — •Anja Tanzke — MPI for Physics, Munich, Germany

The CRESST experiment aims to directly detect Dark Matter in the form of WIMPs. These hypothetical particles are expected to weakly interact via elastic scattering. The deposited energy is measured by the amplitude of the temperature pulse registered with a superconducting transition edge sensor on the scintillating target crystal. Additionally, the particle dependent scintillation light of the target crystal is detected by a cryogenic light detector. The performance of this detector is investigated and optimizations will be presented.
