SP-466 The Star Splitters
 

Hard X-ray and Low Energy Gamma Ray Experiment, HEAO A-4. The A-4 experiment consisted of a modular array of phoswich scintillator detectors, particle monitors, a digital processor containing power conditioning, and data handling electronics. The purpose of the experiment was to determine the position, spectrum, time variations, intensity, and other properties of selected X- and gamma ray sources in the energy range of 10 to 10000 kiloelectron volts. Principal Investigators were Laurence Peterson of the University of California at San Diego (UCSD) and Walter Lewin of MIT. Experiment hardware was provided by UCSD and Time Zero Laboratories of Ball Brothers Research Corporation.
