Low Temperature

Low Temperature R & D

Low temperature sensors have opened up great opportunities by enabling measure-ments of tiny energy depositions from particle interactions. Because of their excellent sensitivity, such sensors have played important roles in rare phenomena searches such as direct dark matter searches and neutrinoless double beta decay experiments. The low temperature group at CUP has developed the AMoRE crystal detectors which use the MMC (Metallic Magnetic Calorimeter) technique to measure phonons and scintillation photons produced by the particle interactions in the crystal. We conduct R&D to improve the performance of the phonon and photon detection using various low temperature techniques. We have tested various Mo-based crystals for the future double beta decay experiment. We are also working on a low temperature facility to accommodate a large detector array and shield structure for the large-scale experiment.
