Abstract
We report on the X-ray response of the X-ray CCD camera X-ray Imaging Spectrometer (XIS) onboard the X-ray Astronomical Satellite, ASTRO-E, which will be launched in February of 2000. The XIS is prepared by an international team, comprising MIT (USA), ISAS, Osaka Univ. and Kyoto Univ. (JAPAN). We evaluate the X-ray response of engineering model (EM) of the XIS at the high energy band of 1.5–10 keV. Fluorescent lines from Al, Cl, Ti, Ni, Fe, Zn are irradiated on the CCD chips, and are used to construct the response function. Details of the response function; energy-scale, linearity, energy resolution, quantum efficiency and etc, are given as a function of incident X-ray energies.
