| Outline of Final Research Achievements |
Recently, there are many dark matter experiments targeting a WIMP dark matter. However, they have not found the evidence of the WIMP dark matter. Thus, we focus on light dark matter under the GeV scale. For that study, low energy threshold detectors are one of the key. We use superconducting detector. We developed fabrication system, low-temperature system, readout system for superconducting detectors. In addition, we validated the detector is sensitive to particle with gamma-ray tests. Therefore, the initial test is find.
