The cosmic X-ray experiment aboard HEAO-1.
Abstract
The cosmic X-ray experiment aboard the HEAO-1 observatory is described, The instrument consists of six gas proportional counters of three types nominally covering the energy ranges of 0.15 keV, 1.2-20 keV, and 2.5-60 keV. The two low energy detectors have about 400 sq cm open area each while the four others have about 800 sq cm each. A novel feature of this experiment is the dual field of view collimators that allow the unambiguous determination of instrument internal background and diffuse X-ray brightness. Instrument characteristics and early performance are discussed.
