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.   Damage and recovery behavior of 4H-SiC implanted with He ions 期刊论文  OAI收割 NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION B-BEAM INTERACTIONS WITH MATERIALS AND ATOMS, 2019, 卷号: 449, 页码: 54-57 作者:  Zhang, Chonghong;  Yang, Yitao;  Su, Changhao;  Ding, Zhaonan;  Song, Yin   |  收藏  |  浏览/下载：112/0  |  提交时间：2019/11/10 4H-SiC  He ions implantation  Nanoindentation  Raman  Graphite  Thermal annealing   Application of FLUKA and OpenMC in coupled physics calculation of target and subcritical reactor for ADS 期刊论文  OAI收割 NUCLEAR SCIENCE AND TECHNIQUES, 2019, 卷号: 30 作者:  Zhao, Ze-Long;  Yang, Yong-Wei;  Hong, Shuang   |  收藏  |  浏览/下载：126/0  |  提交时间：2019/03/27 Accelerator-driven subcritical system  MCNPX  FLUKA  OpenMC  JENDL4  0  HE  NJOY2016   Alpha-clustering effects on O-16(gamma, np)N-14 in the quasi-deuteron region 期刊论文  OAI收割 EUROPEAN PHYSICAL JOURNAL A, 2017, 卷号: 53, 期号: 6, 页码: - 作者:  Huang, BS;  Ma, YG;  He, WB   |  收藏  |  浏览/下载：204/0  |  提交时间：2018/08/30 Nuclear Correlation  Cross-sections  Resonances  Scattering  Facility  Model  He-4   Investigation of Helium Diffusion Behavior in Ti3SiC2 by He-3 (d, p) He-4 Nuclear Reaction 期刊论文  OAI收割 ACTA PHYSICO-CHIMICA SINICA, 2015, 页码: 54-58 作者:  Qi Qiang;  Huang Mengbing;  Zhang Hai-Bin;  Shi Li-Qun   |  收藏  |  浏览/下载：63/0  |  提交时间：2018/05/31 Ti3SiC2 MAX phase  Helium diffusion behavior  He-3 (d, p) He-4 nuclear reaction  Helium bubble  Irradiation damage   Determination of tritium in Li–Pb alloy irradiated by thermal neutrons with quantitatively analyzing the byproduct 4He 期刊论文  OAI收割 J Radioanal Nucl Chem, 2014, 期号: 299, 页码: 733-740 作者:  X.
