ASTRO-H是ISAS/JAXA的一项国际X射线使命，将于2014年发射。ASTRO-H的主要特点之一是10千电子伏以上硬X射线波段的成像光谱学。ASTRO-H将携带两台相同的硬X射线望远镜，其镜面涂有Pt/C深度渐变多层膜，以将硬X射线有效面积提高到80 keV。在对HXT设计进行可行性研究后，确定了FM设计。名古屋大学自2010年8月开始批量生产镜壳，HXT-1的镜壳生产于2012年3月完成。在HXT-1的X射线反射镜集成之后，我们在同步辐射设施SPring-8光束线BL 20 B2上测量了HXT-1所选镜壳的硬X射线性能。我们将在SPring-8为HXT-1进行环境测试和地面校准。在HXT-2中，箔生产正在进行。
ASTRO-H is an international X-ray mission of ISAS/JAXA, which will be launched in 2014. One of the main characteristics of ASTRO-H is imaging spectroscopy in the hard X-ray band above 10 keV. ASTRO-H will carry two identical Hard X-ray telescopes (HXTs), whose mirror surfaces are coated with Pt/C depth-graded multilayers to enhance hard X-ray effective area up to 80 keV.HXT was designed based on the telescope on board the SUMIT balloon borne experiment. After feasibility study of the HXT design, the FM design has been deteremined. Mass production of the mirror shells at Nagoya University has been going on since August 2010, and production of mirror shells for HXT-1 was completed in March 2012. After the integation of X-ray mirrors for HXT-1, we measured hard X-ray performance of selected mirror shells for HXT-1 at a synchrotron radiation facility, SPring-8 beamline BL20B2. We will perform environment tests and ground calibarations at SPring-8 for HXT-1. In HXT-2, foil production is going on.
