文摘

This paper introduces the current configuration of the Hard X-ray Calibration Facility (HXCF) in 2014, which is used to calibrate the high energy X-ray detectors that will be onboard the Hard X-ray Modulation Telescope (HXMT) satellite, China’s first astronomy satellite. The HXCF consists of an X-ray tube, a skid platform system, a double crystal monochromator, a “T-structure mechanism, a collimator, an adjustable beam, a background shielding box, as well as the box of the control system. The HXCF covers 15-00?keV energy band and has a high fraction of monochromatic light (exceeding 92?% at 15-00?keV) and good monochromaticity (1-level). The flux of the monochromatic light is around 104 photons cm? s?. This HXCF could be used to calibrate the energy linearities, the energy resolutions and detection efficiencies of hard X-ray detectors.
