摘要：

The CZT detector on the InFOCmuS hard X-ray telescope is a pixellated solid-state device capable of imaging spectroscopy by measuring the position and energy of each incoming photon. The detector sits at the focal point of an 8m focal length multilayered grazing incidence X-ray mirror which has significant effective area between 20-40 keV. The detector has an energy resolution of 4.0keV at 32keV, and the InFOCmuS telescope has an angular resolution of 2.2 arcminute and a field of view of about 10 arcminutes. InFOCmuS flew on a balloon mission in July 2001 and observed Cygnus X-1. We present results from laboratory testing of the detector to measure the uniformity of response across the detector, to determine the spectral resolution, and to perform a simple noise decomposition. We also present a hard X-ray spectrum and image of Cygnus X-1, and measurements of the hard X-ray CZT background obtained with the SWIN detector on InFOCmuS.
