Cryogenic Heat–Light Detection System for 1-cm³ Scintillating Crystals

We have developed a cryogenic heat and light detection system to investigate phonon and scintillation properties of scintillating crystals for rare event search experiments. The detector setup is designed to utilize a 1 × 1 × 1 cm3 scintillating crystal as a target material. A 1.5 × 1.5 × 0.05 cm3 Ge wafer is used as the absorber of the light detection. Metallic magnetic calorimeters are employed ...
