Abstract
We present recent results of hard X-ray characterization of ASTRO-H HXT at SPring-8. The HXT onboard ASTRO-H is thin-foil, multi-nested conical optics similar to the Suzaku X-ray telescope. To reflect hard X-rays efficiently, reflector surface is coated with depth-graded Pt/C multilayer. The integraion of the HXT-1 mirror module has been completed. This mirror module has been characterized at a synchrotron radiation facility, SPring-8 beamline BL20B2. We have adopted, newly, an active tuning procedure with piezoelectric actuator to improve a focused image confocality. We have measured point spread function and effective area at 30, 40, 50, and 60 keV. An angular resolution of 1.9 arcmin (HPD) at 30 keV was obtained in the full telescope. The effective area of HXT-1 at 30 keV meets the requirements of HXT.
