Abstract

We present the first results of pre-flight calibrations of the X-ray telescopes on board ASTRO-E satellite. They adopt a thin foil-nesting Wolter Type-I optics, which is in principle the same as ASCA XRTs. Owing to a scale up of the telescope and a new technique of the reflector production, however, both the effective area and the imaging capability are improved. In the current measurements, the effective area is obtained to be 460, 315 and 250 cm2 per XRT at 1.49, 4.51, and 8.04 keV, respectively, which is significantly larger than that of ASCA by a factor of 1.5 and 2.5 at 1.49 keV and 8.04 keV. The point spread function also shows a better focusing capability than ASCA by a factor of 2, and the half power diameter is obtained to be 1.84 arcmin at 4.51 keV. The brightness of the stray light is obtained to be 2×10-5 counts s-1 mm-2 at the brightest part of the stray light image, in the case that the X-ray star with the on-axis intensity of 1 count s-1 is the source of the stray lights, which is almost the same with ASCA.
