Outline of Final Research Achievements |
X-ray polarization is the key to search for the spatial structure and emission mechanism around the celestial object in the extreme condition. However, the progress for the polarimetry is considerably delayed because of technical difficulties. In order to make a breakthrough in the field of X-ray polarimetry, we have developed a new type of Bragg crystal polarimeter with the large bent Si crystals. We focused the energy band including the series of Fe-K line emission (~7 keV) to give important information in the X-ray astronomy. It it difficult to bent the crystals with the high accuracy. We succeeded to bent the crystals to the shape of paraboloid and paraboloid of revolution with DLC method and CFRP.
