A charge sensitive preamplifier was realized on high resistivity detector grade silicon. The amplifier operates on a fully depleted bulk of a silicon wafer. As the anode region of any radiation detector operates at the full depletion as well, the pos

Silicon Drift Detectors (SDDs) with integrated readout transistors combine a large sensitive area with a small total readnode capacitance and are therefore well suited for high resolution, high count rate X-ray spectroscopy. The low leakage current l

Fully depleted silicon pn-CCDs with an active thickness of 300 micrometers exhibit a quantum efficiency of 90 percent at a wavelength of 1 micrometers in the near IR. The multi-parallel readout architecture allows for a frame time shorter than 2 ms f

The principle of sideward depletion introduced 1984 by E. Gatti and P. Rehak, is the milestone for the realization of thesilicon drift detector (SDD). Thanks to the low capacitance associated with the readout anode, obtained by the integration of the

On 10th December 1999, the European X-ray satellite XMM, now called XMM-Newton, was successfully put into orbit. After initial commissioning of the satellite's subsystems, the EPIC-pn camera was switched on and tested thoroughly in the period Jan./Fe

XMM-Newton, the most powerful X-ray telescope ever built was launched from the european space port Kourou on december 10 last year. Three large X-ray Wolter type mirror systems are focusing the incoming X-rays from 100 eV up to 15,000 eV onto the foc

Large format arrays covering a wide bandwidth from 1 eV to 25 keV will be used in the focal plane of X-ray telescopesas well as in adaptive optics systems. As the readout speed requirements increase drastically with the collecting area, but noise fig
