Description
We are conducting a low-mass dark matter search at the Kamioka Underground Observatory, targeting dark matter in the sub-GeV mass regime. The experiment employs Transition Edge Sensor (TES)–based cryogenic detectors to measure tiny signals from particle interactions in a liquid helium target operated at ultra-low temperatures. Underground operation at 2700 m.w.e., together with dedicated gamma and neutron shielding, provides the low-background environment required for this search. This presentation will give an overview of the experimental concept and current status, with a focus on recent progress in background estimation, detector installation, and on-site preparation.
