Development of cryogenic phonon detectors based on CaMoO4 and ZnWO4 scintillating crystals for direct dark matter search experiments

摘要

This work reports on the development of the first phonon detectors based onCaMoO4 and ZnWO4 scintillating crystals for the CRESST-II experiment. Inparticular, a novel technique for the production of the ZnWO4 phonon detectorwith a separate thermometer carrier was investigated. The influence of thethermal and mechanical treatment on the scintillation light output of CaMoO4and ZnWO4 crystals at room temperature is discussed.
