Paper Abstract
The international X-ray observatory, ASTRO-H is currently planed as launched in 2015. The ASTRO-H mission covers a wide energy range from a few hundreds eV to 600 keV. The two Soft X-ray Telescopes (SXT- 1 and SXT-2) play a role to image the soft X-ray sky up to ~12 keV in that range. Each of them focuses an image on the focal plane detectors of the CCD camera (SXI) and the calorimeter (SXS-XCS), respectively. In this paper, we present spot scan measurements of the two SXTs. The spot scan fully illuminates the telescope by mapping with the 8 mm by 8 mm beam and creates the ”maps” of the half power diameter (HPD) and the focal location of the focused image. We found variations of performance at local area of the telescope. Each of the spot images has different focal-location and different HPD. Moreover, we found that the map of the HPD is very similar from quadrant to quadrant, but the map of the focal location is different from quadrant to quadrant, from radius to radius, and from azimuthal angle to angle.
