Outline of Final Research Achievements

We have developed emulsion telescope in order to observe cosmic gamma-ray with high angular resolution and polarization sensitivity, which has been launched by JAXA international balloon experiment campaign at Alice Springs, Australia. We have established collaboration system to perform day-order duration observation and recovery of the emulsion telescope. We also established the method to analyze massive data of electron-positron pair accumulated by gamma-ray in the emulsion telescope. From real data of 100-200 MeV region during flight, we confirmed the realization of expected angular resolution using back-ground gamma-rays accidentally produced internally in the emulsion telescope itself or external structure of balloon system.
