| Outline of Final Research Achievements |
In order to confirm the non-thermal X-ray emission from accelerated particles, hard X-ray (20-60 keV) imaging polarimetry balloon experiment "X-Calibur" was performed with groups in USA. Hard X-ray telescope and a day time star camera were developed by Nagoya University. Gondola was prepared by a NASA group, and the polarimeter was developed by a group of Washington University. In 2013, flight was not done because of bad wind condition in the launch window. In September 2014, the flight was successfully performed for 9.5 hours. Though the star camera worked well, pointing observation was not possible. The detector detected X-ray sky background and the observed counting rate was close to expected one after the noise reduction logics. Based on the present flight, next flight in September 2016 and a proposal of polarimetry satellite mission are being considered.
