Abstract

ASTRO-D is the next X-ray mission in Japan. The main instrument of ASTRO-D is 4 sets of thin foil conical mirrors with focal plane detectors of CCDs and Imaging Gas Scintillation Proportional Counters (IGSPC). The total effective area of the 4 mirrors is about 500 cm2 at 6 - 7 keV, with energy resolutions about 2% (FWHM) and 8% (FWHM) at 6 keV for CCD and IGSPC, respectively. The spatial resolution of the mirror is 2-3 arcmin in half power diameter, having a field of view of about 30 arcmin diameter. ASTRO-D will provide us with a unique and powerful capability to study high energy astrophysics in the early 1990s.
