Three different types of proportional gas detectors under development at the Danish Space Research Institute for use in X-ray astronomy are discussed. They are a conventional multiwire proportional counter, a novel microstrip detector, and a parallel gap counter with a segmented anode readout. Instead of wires, the microstrip counter employs very narrowly spaced conducting strips deposited on an isolating substrate. Excellent energy resolutions have been achieved with this detector. Several possible methods for position readout for this detector are described. The parallel gap detector is equipped with a wedge and strip electrode as the anode and has been operated with gas amplifications up to 100,000. The signals induced in the segmented anode permit accurate two-dimensional position determination.
