欧洲光子成像照相机（EPIC）联盟为XMM-牛顿上的三个X射线镜系统提供了焦平面仪器。两个相机的反射光栅光谱仪的光路配备了MOS型CCD作为焦平面探测器（特纳2001年），望远镜与全光子通量操作的新型pn-CCD作为成像X射线光谱仪。pn-CCD照相机系统是在德国马克斯-普朗克研究所的领导下研制的。本文介绍了pn-CCD照相机系统的概念以及照相机系统的不同工作模式。简要介绍了焦平面和相机的电气、机械和热设计。从能量分辨率、量子效率、时间分辨率、长期稳定性和带电粒子背景等方面描述了在轨性能。特别强调了这些设备的辐射加固以及在轨运行头9个月电离粒子辐射损害造成的实测和预期退化。
The European Photon Imaging Camera (EPIC)consortium has provided the focal plane instruments for the three X-ray mirror systems on XMM-Newton. Two cameras with a reflecting grating spectrometer in the optical path are equipped with MOS type CCDs as focal plane detectors (Turner 2001), the telescope with the full photon flux operates the novel pn-CCD as an imaging X-ray spectrometer. The pn-CCD camera system was developed under the leadership of the Max-Planck-Institut fur extraterrestrische Physik (MPE), Garching, The concept of the pn-CCD is described as well as the different operational modes of the camera system. The electrical, mechanical and thermal design of the focal plane and camera is briefly treated. The in-orbit performance is described in terms of energy resolution, quantum efficiency, time resolution, long term stability and charged particle background. Special emphasis is given to the radiation hardening of the devices and the measured and expected degradation due to radiation damage of ionizing particles in the first 9 months of in orbit operation.
