The Physics Department of the TUM operates a shallow underground detector laboratory (UGL) in Garching, Germany. It provides ∼ 160 m2 of laboratory space which is shielded from cosmic radiation by ∼ 6 m of gravel and soil, corresponding to ∼ 15 m.w.e.. The laboratory houses a cleanroom (class ISO 7) equipped for fabrication and assembly of cryogenic detectors. Furthermore, the UGL runs a 3He-4He dilution refrigerator. The infrastructure is particularly relevant for the characterization of CaWO4 target crystals for the CRESST-III experiment, detector fabrication and detector assembly for rare event searches. Future applications include detector development in the framework of coherent neutrino nucleus scattering experiments (ν-cleus) and studying its potential as a site to search for MeV-scale Dark Matter with gram-scale cryogenic detectors. 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.
