Description
We developed a low threshold detector for low mass dark matter search with a CaF2 crystal and an MMC readout. The detector was assembled to make a direct metal-metal contact between an MMC sensor and a phonon-collector film on the crystal. This new absorber-sensor geometry resulted in a signal rise-time of about 100 us and a detection threshold of about a few tens of eV. We present the detector performance and the results of an above-ground measurement for the direct detection of low-mass dark matter
