摘要:

雅典纳X射线观测站是一个计划中的多国轨道X射线观测站,焦距为11.5米。ATHENA旨在以高灵敏度在0.1 keV至15 keV的能量范围内进行定点观测。对于高空间和时间分辨率的成像和光谱观测,基于640 × 640像素^2大DePFET技术的宽视场成像仪(WFI)焦平面探测器将是主要探测器,它提供18弧秒的视场。基于实际的力学、热学和屏蔽设计,我们提出了使用蒙特卡罗模拟获得的WFI宇宙线诱导本底的估计和可能的本底降低措施。

英文摘要:

The ATHENA X-ray Observatory-IXO is a planned multinational orbiting X-ray observatory with a focal length of 11.5m. ATHENA aims to perform pointed observations in an energy range from 0.1 keV to 15 keV with high sensitivity. For high spatial and timing resolution imaging and spectroscopic observations the 640x640 pixel^2 large DePFET-technology based Wide field Imager (WFI) focal plane detector, providing a field of view of 18 arcsec will be the main detector. Based on the actual mechanics, thermal and shielding design we present estimates for the WFI cosmic ray induced background obtained by the use of Monte-Carlo simulations and possible background reduction measures.
