Abstract |
As China’s first X-ray astronomical satellite, Insight-HXMT (Hard X-ray Modulation Telescope) successfully launched on Jun 15, 2017. It carries three main payloads onboard: the High Energy X-ray telescope (HE, 20-250keV, NaI(Tl)), the Medium Energy X-ray Telescope (ME, 5-30keV, SiPin) and the Low Energy X-ray telescope (LE, 1-15keV, SCD). In orbit, we have used the radioactive sources, activated lines, the fluorescence line and Cas A to calibrate the gain and energy resolution. The Crab pulsar was used as the primary effective area calibrator and an empirical function was found to modify the simulated effective areas. The absolute timing of HXMT is about 100us. The peak pointing direction of the collimators is known to a precision of a few arcseconds. |
