摘要：

We present X-ray characteristics of X-ray telescopes (XRTs) onboard the Astro-E2 satellite. It is scheduled to be launched in February 2005. We have been performed X-ray characterization measurements of XRTs at Institute of Space and Astronautical Science (ISAS) since January 2003. We adopted a raster scan method with a narrow X-ray pencil beam. Angular resolution of the Quadrants composed of the Astro-E2 XRT was evaluated to be 1'.6 - 2'.2 (HPD: Half Power Diameter), irrespective of the X-ray energy while those of the Astro-E2 XRT was 2'.0 - 2'.2. The effective area of a telescope is approximately 450, 330, 250, and 170 [cm(2)] at energies of 1.49, 4.51, 8.04, and 9.44 keV, respectively. The field of view (FOV) of the XRTs which is defined as Full Width Half Maximum (FWHM) of the vignetting function is similar to 18 ' at 4.51 keV. We summarize these characters of the XRTs.
