It has three collimated telescopes, the High Energy X-ray telescope (HE), the Medium Energy X-ray telescope (ME), and the Low Energy X-ray telescope (LE). Before the launch, in-orbit backgrounds of these three telescopes had been estimated through Geant4 simulation, in order to investigate the instrument performance and the achievement of scientific goals. In this work, these simulated backgrounds are compared with in-orbit observations. Good agreements are shown for all three telescopes. For HE, (1) the deviation of the simulated background rate after two years of operation in space is 5 % from the observation  (2) the total background spectrum and the relative abundance of the 67 keV line show long-term increases both in simulations and observations. For ME, (1) the deviation of simulated background rate is within 15 % from the observation, and (2) there are no obvious long-term increase features in the background spectra of simulations and observations. For LE, the background level given by simulations is also consistent with observations. The consistencies of these comparisons validate that the Insight-HXMT mass model, i.e., space environment components and models adopted, physics processes selected, and detector constructions built, is reasonable. However, the line features at 7.5 and 8.0 keV, which are obvious in the observed spectra of LE, are not evident in simulations. This might result from uncertainties in the LE constructions.   First performance test of a 30mm iron-based superconductor single pancake coil under a 24T background field 期刊论文  OAI收割 SUPERCONDUCTOR SCIENCE & TECHNOLOGY, 2019, 卷号: 32, 期号: 4, 页码: 5 作者:  Wang, Dongliang;  Zhang, Zhan;  Zhang, Xianping;  Jiang, Donghui;  Dong, Chiheng   |  收藏  |  浏览/下载：26/0  |  提交时间：2020/07/14 iron-based superconductor  single pancake coil  high background field  transport performance  wind-and-react method   First performance test of a 30 mm iron-based superconductor single pancake coil under a 24 t background field 期刊论文  iSwitch采集 Superconductor science and technology, 2019, 卷号: 32, 期号: 4 作者:  Wang,Dongliang;  Zhang,Zhan;  Zhang,Xianping;  Jiang,Donghui;  Dong,Chiheng 收藏  |  浏览/下载：75/0  |  提交时间：2019/04/23 Iron-based superconductor  Single pancake coil  High background field  Transport performance  Wind-and-react method   X-ray background and its correlation with the 21 cm signal 期刊论文  OAI收割 MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY, 2018, 卷号: 480, 期号: 1, 页码: 26-34 作者:  Ma, Q.;  Ciardi, B.;  Eide, M.
