| Outline of Final Research Achievements |
The type Ia supernovae or the active galactic nuclei are expected as the origin of extragalactic diffuse gamma-rays. However, the observation in the MeV region is not advanced enough to determine the origin. For obtaining a detail energy spectrum, we developed a new MeV gamma-ray telescope, electron-tracking Compton camera (ETCC). An ETCC, which is a kind of the Compton cameras, can decide the incident direction photon by photon utilizing the tracks of the Compton-recoil electrons. The developed ETCC was loaded on a balloon, and it was launched from Australia on April, 2018. The balloon flown at the altitude of approximately 40 km during 26 hours. The ETCC was operated stably during this flight, and it was successful to observe the gamma-rays at the balloon altitudes.
