抄録（英）
We have been developing a hard X-ray polarimeter with high sensitivity, called as a PHENEX (Polarimetry for High ENErgy X-rays) polarimeter. We constructed prototype PHENEX polarimeter and carried out a preliminary observation of the Crab Nebula on June 13th, 2006 as a balloon-borne experiment. Though we confirmed from the data that PHENEX polarimeter detected hard X rays from the Crab Nebula with a significance of 8 sigma, the degree and the direction of polarization with high accuracy could not be determined because of the trouble for attitude control system (ACS) and the small detection area of the prototype polarimeter. We improved the PHENEX polarimeter and carried out a balloon-borne experiment in June 2009 launching from Taiki Aerospace Research Field to observe the polarization of the Crab Nebula with higher accuracy. In this paper, we will report the summary of this experiment.
