通过Geant4模拟对雅典娜X-IFU仪器的背景进行了评估。已经制作了一个新的、高度详细的X-IFU及其低温恒温器的质量模型，一个关于L2中银河宇宙线质子的新模型已经从卫星数据中开发出来，一套符合雅典娜需要的物理模型已经通过与实验结果的广泛验证而得到完善。我们将报告在更新Geant4模拟和后处理软件的所有元素后获得的X-IFU仪器本底估计的最新结果。
The background of the ATHENA X-IFU instrument is evaluated by Geant4 simulations. A new, highly detailed, mass model of the X-IFU and of its cryostat has been produced, a new model for the Galactic Cosmic Ray protons in L2 has been developed from satellite data, and a set of physics models tuned to ATHENA needs has been refined through extensive validations against experimental results. We are going to report the latest results in the estimate of the background of the X-IFU instrument, obtained after the update of all the elements of the Geant4 simulations and of the post processing software.
