Abstract

Three different types of proportional gas detectors are under development at the Danish Space Research Institute for use in X-ray astronomy. A conventional multiwire proportional counter, a novel microstrip detector and a parallel gap counter with a segmented anode readout. Instead of wires, the micro strip counter employs very narrowly spaced conducting strips deposited on an isolating substrate. Excellent energy resolutions of 13% (5.9 keV) and 27% (1.5 keV) have been achieved. Several possible methods for position readout for this detector are reported. The parallel gap detec-tor is equipped with a wedge and strip electrode as the anode and has been operated with gas amplifications up to 105. The signals induced in the segmented anode allow for accurate two-dimensional position determination.
