The German X-ray observatory eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the prime instrument of the new Spectrum-RG mission. Launch of the Russian satellite is planned for the year 2011. The scientific goal of eROSITA is primarily the detection and analysis of 100 thousand clusters of galaxies in order to study the large scale structures in the Universe and to test cosmological models. The therefore required large effective area is obtained by an array of seven identical and parallel aligned Wolter-I telescopes. In the focus of each mirror module, there is a large frame store pnCCD detector, providing a field of view of 1° in diameter. The same X-ray detector type will also be applied for ART-XC, another grazing-incidence telescope system aboard Spectrum-RG, which permits the detection of heavily obscured X-ray sources. These scientific instruments allow the exploration of the X-ray Universe in the energy band from 0.3 keV to 11 keV. During a mission time of at least five years, an all-sky survey, wide as well as deep surveys and pointed observations will be performed. Approval and funding for eROSITA were granted by the German space agency DLR in April 2007. The conceptual design of the X-ray focal plane cameras is presented here comprising electrical, thermal, and mechanical aspects. Key part of the camera is the pnCCD detector chip, which is developed and produced in our semiconductor laboratory, the MPI Halbleiterlabor. The CCD was designed according to the specifications given by the scientific goals of eROSITA. The eROSITA CCD differs apparently from all previously produced frame store pnCCDs by its larger size and format. The CCD image area of the seven eROSITA cameras is in total 58 cm² large and their number of pixels is about seven times higher than that of the XMM-Newton pnCCD camera. First pnCCD devices were recently produced and tested. Their performance measurements and results are of most importance for eROSITA because the tested CCDs are the control sample of the flight detector production.

The pn-charge coupled device (pn-CCD) detector system was developed as the focal plane instrument of an x-ray telescope for the European photon imaging camera (EPIC) on the x-ray multi mirror (XMM) mission. The second cornerstone mission of the European Space Agency's Horizon 2000 plan performs high throughput imaging and spectroscopy of the x- ray sky in the domain of 0.1 keV - 15 keV. The pn-charge coupled device will also be used for a German x-ray astronomy satellite mission, called ABRIXAS (a broad-band imaging x-ray all-sky survey). While XMM will perform pointed observations. ABRIXAS will carry out an all sky survey with imaging telescopes. Both projects are planned to be launched in 1999. The homogeneous coherent sensitive area of the detector consists of a 6 cm by 6 cm large array of 12 pn-CCDs which are monolithically integrated on a single silicon wafer together with the first stage of amplification. The pn-CCD detector has been optimized for high-resolution x-ray spectroscopy and its performance is close to the theoretical limits given by the Fano noise. High quantum efficiency essential for the investigation of faint objects is accomplished over the whole energy range by a thin photon entrance window and a full sensitive detector thickness. A fast readout achieves excellent time resolution for the observation of pulsed x-ray sources and avoids pile- up for bright objects. The relevant performance parameters reflecting the state of the detector development are presented. The radiation hardness of the pn-CCD was verified for the ten year satellite mission. No significant increases in the thermally generated current, charge transfer losses and transfer noise occurred in the temperature range planned for detector operation. A correction of the signal charge losses, which occur already before irradiation in all types of charge coupled devices during the charge transfer to the anodes, is necessary to achieve the highest energy resolution of the detector. Methods to reduce the signal charge losses which were successfully tested, are described.
