The 100-m X-ray test facility at IHEP

Abstract The 100-m X-ray Test Facility of the Institute High Energy Physics (IHEP) was initially proposed in 2012 for test and calibration detectors Hard Modulation Telescope (HXMT) with capability to support future missions. large instrument chamber connected a long vacuum tube can accommodate mirror, focal plane detector other instruments. sources are installed at end distance 105 m, which provide an almost parallel beam covering 0.2 $$\sim$$ ∼ 60 keV energy band. mirror modules Einstein Probe (EP) enhanced Timing Polarimetry mission (eXTP) payload Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM) have been tested calibrated this facility. It has also used characterize camera aluminum filter on Probe. In paper, we will introduce overall configuration facility, give brief introduction some results performed
