摘要：

The ASTRO-E X-ray Imaging Spectrometers (XISs) consists of four sets of X-ray CCD camera for the ASTRO-E mission. The XISs have been calibrated at Osaka University: KJ oto University, ISAS and MIT. The calibration experiment. at, Osaka focuses on the soft, X-ray response of the XIS (from 0.25 to 2.2 keV). The calibration of the XIS Flight Model (XIS FM) has been performed since: August 1998. We measured the signal-pulse height, the energy resolution and the quantum efficiency of the XIS as a function of energy of which are essential to construct the response function of the XIS. The detailed shape of the pulse-height-distribution, are also investigated. We also constructed a numerical simulator of the XIS, which tracks the physical processes in the CCD so as to reproduce the measured data. With a help of this simulator, we propose a model for the pulse-height-distribution of the XIS for single energy incident X-rays. The model consists of four components; two Gaussians, a constant, plus a triangle-shape component.
