Paper Abstract

Detector systems based on the high-gain microchannel plate (MCP) electron multiplier have been used extensively for imaging at soft x-ray wavelengths both on the ground and in space. The latest pulse-counting electronic readout systems provide zero readout-noise, spatial resolutions (FWHM) of 25 microns or better and can determine the arrival times of detected photons to an accuracy of the order of 100 ns. These systems can be developed to produce detectors with active areas of 100 mm in diameter or greater. The use of CsI photocathodes produces very high detective quantum efficiencies at wavelengths between about 100 and 1Å (~0.1 to 10 keV) with moderate energy resolution. The operating characteristics of the different types of soft x-ray MCP detector systems are described and the prospects for future developments are discussed.
