为欧洲XMM卫星任务和德国ABRIXAS任务研制了一个6 cm × 6 cm的大型单片电荷耦合装置作为焦平面X射线探测器。这种光谱硅探测器被命名为pn- ccd，因为它使用反向偏置pn结作为电荷转移寄存器，作为超薄均匀光子入口窗口和片上电子器件。由于pn-CCD的概念，整个300微米的晶圆厚度对电离辐射非常敏感。读出是并行执行的，对于36平方厘米的大检测器区域只需要73毫秒。片上集成的JFET电子器件实现了均匀的低噪声性能。两个最好的pn- ccd已经集成在XMM和abrixas的飞行相机中，并在空间中进行了长期运行的广泛测试。该报告包括探测器的基本概念，对飞行装置及其制造，测试和操作以及关键性能参数的简要描述。最后展望了进一步发展的方法。
A 6 cm X 6 cm large monolithic charge coupled device has been developed and fabricated as focal plane x-ray detector for the European XMM satellite mission and the German ABRIXAS mission. This spectroscopic silicon detector is denominated pn-CCD because of its use of reverse biased pn- junctions as charge transfer registers, as ultra-thin homogeneous photon entrance window and for the on-chip electronics. Due tot he pn-CCD concept, the whole wafer thickness of 300 micrometers is sensitive to ionizing radiation. The read-out is performed in parallel and needs only 73 ms for the 36 cm2 large detector area. A uniform low noise performance is realized by on-chip integrated JFET electronics. The two best pn-CCDs have been integrated in the flight cameras for XMM and abrixas and extensively tested for the long term operation in space. The presentation comprises the basic concept of the detector, a short description of the flight device and its fabrication, test and operating as well as the key performance parameters. The concluding outlook describes methods of further development of the pn-CCD.
