A PROGRAM OF RESEARCH FOR THE MEASUREMENT OF COSMIC X-RAYS FROM ROCKET-BORNE INSTRUMENTATION.

Abstract

Rocket experiments were flown during October 1962 and June 1963 that confirmed the existence of substantial fluxes of soft X-rays in the night sky apparently of galactic origin. There is evidence for more than one distinct source as well as for a background of X-rays. The X-ray detectors used in these experiments consisted of Geiger counters sensitive in the 2 to 8 angstrom range and scintillation counters sensitive in the 0.1 to 1 angstrom range. An additional rocket payload was developed to measure X-ray emission from the Moon extending to 44 angstrom. This payload involved a novel detection scheme that made use of the external photo effect on alkali halide surfaces. (Author)
