论文摘要
我们介绍了洞察力X射线调制望远镜（Insight-HXMT）X射线卫星的校准，该卫星可用于执行明亮X射线源的定时和光谱研究。 Insight-HXMT在船上带有三个主要有效载荷：高能X射线望远镜（HE），中型能量X射线望远镜（ME）和低能X射线望远镜（LE）。在轨道上，放射性源，激活线，荧光线和天体来源用于校准有效载荷的能量尺度和能量分辨率。螃蟹nebular被用作主要有效区域校准器，并构建了经验功能，以分别修改三个有效载荷的模拟有效区域。与螃蟹nebular的模型相比，HE的系统误差在28--120 KEV中不到2％，而2％-120 KEV高于120 KEV。在10--35 KEV中，我的系统错误小于1.5％。 LE的系统误差在1--7 KEV中的1％少于1％，除了Si K--边缘（1.839 KEV，高达1.5％），在7--10 KEV中的keV不到1％。
We present the calibration of the Insight-Hard X-ray Modulation Telescope (Insight-HXMT) X-ray satellite, which can be used to perform timing and spectral studies of bright X-ray sources. Insight-HXMT carries three main payloads onboard: the High Energy X-ray telescope (HE), the Medium Energy X-ray telescope (ME) and the Low Energy X-ray telescope (LE). In orbit, the radioactive sources, activated lines, the fluorescence lines and celestial sources are used to calibrate the energy scale and energy resolution of the payloads. The Crab nebular is adopted as the primary effective area calibrator and empirical functions are constructed to modify the simulated effective areas of the three payloads respectively. The systematic errors of HE, compared to the model of the Crab nebular, are less than 2% in 28--120 keV and 2%--10% above 120 keV. The systematic errors of ME are less than 1.5% in 10--35 keV. The systematic errors of LE are less than 1% in 1--7 keV except the Si K--edge (1.839 keV, up to 1.5%) and less than 2% in 7--10 keV.
