Session 14 - Real Calibrations.

XRS is the microcalorimeter X-ray detector aboard the US-Japanese ASTRO-E observatory, which is scheduled to be launched in early 2000. In addition to XRS, ASTRO-E carries 4 X-ray CCD detectors and a hard X-ray detector. The CCDs are located at the focus of grazing incidence X-ray mirrors and will primarily provide imaging over 0.4-12 keV bandpass. XRS also utilizes an X-ray mirror to focus X-rays onto a 6x6 array of microcalorimeter pixels for high resolutuion spectroscopy with limited spatial resolution. The XRS instrument has an energy resolution of about 12 eV at 6 keV for the nominal operating temperature of 65 mK. Here we present the results of our first calibration of the XRS instrument. We will describe the basic operation of XRS and the methods used to determine the spectral redistribution of the detector and the overall detection efficiency.
