Background discrimination of EDELWEISS-III cryogenic Ge-detectors for dark matter search

Schmidt, Benjamin Ernst Ludwig

Abstract:
The EDELWEIS-III experiment is a direct dark matter search experiment using cryogenic Ge detectors with dual signal readout in ionization and heat for particle identification and background suppression. Within this thesis, a new data analysis framework has been developed. It features an automatic database driven processing and improved ionization signal filtering. A verification of the processing has been done and the focus of the thesis has been set on the analysis of surface backgrounds.
