Abstract

This proceeding presents the CONRAD high-purity germanium spectrometer with a large diode (2.2 kg mass) employing electrical cryocooling. The detector is an ideal tool to characterize background up to high energies of ∼12 MeV. The detector itself exhibits a high level of radiopurity. Due to the cryocooling the detector is flexible and of low maintenance effort. It can be deployed for example at nuclear reactors for site characterization such as for the CONUS experiment, which is looking for coherent elastic neutrino nucleus scattering.
