SP-466 The Star Splitters
 

Gamma Ray Spectrometer, HEAO C- 1. The Gamma Ray Spectrometer consisted of a cluster of four cooled, high-purity germanium detectors in a cesium-iodide sodium-activated shield. The germanium crystals are cooled by a solid cryogen refrigerator. The goal of the experiment was to explore for sources of X-ray and gamma ray line emissions. The instrument measured the spectrum and intensity of both diffuse and discrete sources of X- and gamma radiation. It also measured the isotropy of the diffuse background as well as time variations in the gamma ray flux from discrete sources. The Principal Investigator was Allan Jacobson of NASA's Jet Propulsion Laboratory in Pasadena, California.
