A sealed position sensitive proportional counter filled with two atmospheres of 95 % xenon and 5 % methane, and containing a drift region of 25 atm cm, has operated in a stable manner for many months. The detector contains G-10 frames to support the anode and cathode wires. The detector was sealed successfully by a combination of vacuum baking the G-10 frames at 150 Cel for two weeks followed by assembly into the detector in an environment of dry nitrogen, and the use of passive internal getters. The counter is intended for use with a circumferential cylindrical collimator containing many random slit openings. Together they provide a very broad field of view detection system with the ability to locate cosmic hard X-ray and soft gamma ray sources to an angular precision of a minute of arc. A set of instruments based on this principle have been prposed for satellites to detect and precisely locate cosmic gamma ray bursts.
