Dark Matter Search with Superconducting Detector

WIMP dark matter searches in GeV order mass range is led by xenon detectors. Moreover, searches for light (sub-GeV and MeV) dark matter are planning or ongoing with lighter targets, such as silicon nucleus. An experiment to search dark matter to keV mass region is planned. To lower energy threshold, electrons in superconductor will be used as targets. Energy gap of cooper-pair is enough small to observe keV dark matter. Superconducting detector KID will be used for readout. Detector design, setup and commissioning will be performed. Here, experimental concept and status is reported.
