| Popis: | ESA’s future X-ray mission (launch: ≈ 2010), the X-ray evolving universe spectroscopy mission (XEUS), is under study as a potential successor to the XMM satellite (launch: 15 Dec. 1999). Its collecting area for X-rays from 100 eV up to 20 keV will be about 200 times larger than the XMM. The angular resolution will be improved by a factor of five, the field of view will eventually be as large as 10 arcmin. Novel wide field imagers (WFI) are needed to overcome the limitations by the state-of-the-art CCD type detectors, limited due to the high number of X-rays focussed into the focal plane. To face the problem of high count rate and large formats with simultaneous good energy resolution and high quantum efficiency we have proposed two new focal plane X-ray detectors: (a) a back illuminated active pixel sensor (DEPMOS) and (b) a 2000 readout channel back illuminated frame store pn-CCD. Both will be made at the MPI semiconductor lab on 500 micron high resistivity silicon. From wavelengths from the infrared to X-rays, the detector will have a high quantum efficiency, high speed and low noise performance. |
