| Outline of Final Research Achievements |
We evaluated the imaging performance of the emulsion gamma-ray telescope using the flight data of the balloon-borne experiment, which was performed in 2015. The emulsion telescope detected signals from a calibration source (gamma rays from the interaction of cosmic rays with an aluminum plate, which was situated 4.4 m above the telescope) with a high significance during the balloon observation and created a gamma-ray image consistent with the source size and the expected angular resolution in the energy range of 100-300 MeV. The flight performance proves that balloon-borne emulsion telescope experiments with larger area are feasible while maintaining expected imaging performance.
