Abstract
We have developed a large-area coded-mask telescope for hard-X-ray ast ronomy. The heart of the instrument is an imaging microstrip-gas-count er of active area 30 cm x 30 cm and filled with 2 x 10(5) Pa of xenon + 2% isobutylene. Fabricated on a single sheet of borosilicate glass, 1 mm thick, the microstrip features fine anodes (10 mu m) and interlea ved cathodes from which the position sensing is derived. Rear pickup e lectrodes provide the second coordinate. Full details of the instrumen t and its performance are presented. A first flight, from a high-altit ude balloon, is scheduled for the Spring of 1997.
