摘要：

XIS ( X-ray Imaging Spectrometers) are four sets of X-ray CCD cameras, installed on the focal plane of the X-ray telescopes of ASTRO-E satellite, which will be launched in February, 2000. We have been calibrating the low energy ( 0.25 - 2.2 keV) response of the XIS using a spectrometer system in Osaka University. In this paper, we report the results of the calibration of the XIS EM ( Engineering Model ). We confirmed the energy resolution is about 130 eV at 5.9 keV (FWHM) and readout noise is similar to 3 - 4 electrons (rms) at -90 degrees C, And we measured the XIS response and energy resolution as a function of incident X-ray energy from 0.25 keV to 2.2 keV almost continuously, and absolute quantum efficiency. Based on the procedure we established, we are going to calibrate the XIS FM starts from August, 1998.
