| Research Abstract |
We have developed hard X-ray polarimeter with high sensitivity. In 2009, we have launched it with balloon from Taiki Station in Hokkaido. There are two aims for this experiment. The first one is to confirm the stable operation of the detector. The other one is to observe polarization of hard X-rays from the Crab Nebula. Unfortunately, the wind condition was bad and the attitude control did not work correctly. Therefore the observation for the Crab Nebula had not been carried out. However, we have accomplished the first aim. From this experiment, we can open the way to develop the polarimeter installed on a satellite.
