An All-Sky X-Ray Monitor for the UK-5 Satellite

An x-ray imaging system using a pin-hole camera and a position sensitive proportional counter at the image plane has been designed for an all-sky x-ray monitor for UK-5 satellite. This high-sensitivity device with real-time coverage of the entire celestial sphere would aid in programming satellite maneuvers such that transient events in the x-ray sky could be investigated in detail by the other primary satellite experiments. Discussion of design criteria for the camera geometry, the position sensitive proportional detector, and electronics to handle the data are presented in this paper.
