Description

We have developed a large-area coded-mask telescope for hard-X-ray astronomy. The heart of the instrument is an imaging microstrip-gas-counter of active area 30 cm x 30 cm and filled with 2 x 10 Pa of xenon+2% isobutylene. Fabricated on a single sheet of borosilicate glass, 1 mm thick, the microstrip features of the fine anodes (10 μm) and interleaved cathodes from which the position sensing is derived. Rear pickup electrodes provide the second coordinate. Full details of the instrument and its performance are presented. A first flight, from a high-altitude balloon, is scheduled for the Spring of 1997. (orig.)
