本文介绍了在第二拉格朗日点(L2)轨道上飞行的一颗天文卫星上的X射线微量热谱仪(XMS)对银河系(GCR)和太阳源粒子的影响的研究结果。本文中介绍的详细配置是国际X射线天文台(IXO)研究所采用的配置,但所得出的估计值可被视为ATHENA的保守限制,ATHENA是向欧空局建议的IXO重新定义的使命。这项工作的目的是估计剩余的背景水平预期焦平面探测器在使命的寿命,在任何仪器配置,优化XMS的科学性能的发展的一个关键信息。我们使用Geant4工具包,基于蒙特卡罗的模拟器,调查的排斥效率的反符合系统和评估检测器上的残留背景。
We present the results of a study on the impact of particles of galactic (GCR) and solar origin for the X-ray Microcalorimeter Spectrometer (XMS) aboard an astronomical satellite flying in an orbit at the second Lagrangian point (L2). The detailed configuration presented in this paper is the one adopted for the International X-ray Observatory (IXO) study, however the derived estimates can be considered a conservative limit for ATHENA, that is the IXO redefined mission proposed to ESA. This work is aimed at the estimate of the residual background level expected on the focal plane detector during the mission lifetime, a crucial information in the development of any instrumental configuration that optimizes the XMS scientific performances. We used the Geant4 toolkit, a Monte Carlo based simulator, to investigate the rejection efficiency of the anticoincidence system and assess the residual background on the detector.
