| Outline of Final Research Achievements |
The origin of dark matter can be constrained by observation of 511keV line gamma rays produced by annihilation of positrons generated by dark-matter annihilation. The purpose of this study is to investigate the feasibility of scintillator-based sensitive Compton camera optimized for observation of 511keV gamma rays. The energy resolutions and the angular resolutions were measured by using various candidate scintillators and photon detectors. The detector simulation with the measurements of the scintillators was carried out, indicating large effective area with good angular resolution if a large number of readout channels are available.
