| Abstract(in English) | We have developed an indium-targeted superconducting detector system for real-time observation of pp-neutrinos. pp neutrinos are produced by the pp chain fusion reaction, which is responsible for 99% of the solar energy. Measuring their energy spectrum is important for elucidating the inner structure of the Sun and determining neutrino oscillation parameters, but there have been few detections due to their low termination energy of 0.43 MeV. However, a new detector combining indium and MKID, a superconducting detector, can clearly distinguish pp-neutrino events from background events. In this technical report, we report on the fabrication and sensitivity measurement of MKID, the estimation of detection efficiency by simulation, and the development of a connection method between MKID and an In target using a laser microstructure formation technique. |
