Abstract
Japan's sixth X-ray satellite mission ASTRO-H is planned to be launched in 2014. Hard X-ray Telescope (HXT) to cover hard X-rays up to 80 keV is thin-foil, multi-nested conical optics with depth-graded Pt/C multilayer. The mass production of the reflectors for the flight model has been going on since August 2010. We have introduced a new screening method for replication mandrels with optical imagers. In addition, we have adopted a new replication mandrel which consists of glass tube coated with thin glass sheet for large size mandrels. The selected 212 pairs (95 pairs (segment 1), 59 pairs (segment 2), 58 pairs (segment 3)) of multilayer mirror have been characterized at a large synchrotron radiation facility, Spring-8 beamline BL20B2. We present the current status of reflector production and hard X-ray characterization for HXT.
