The Cosmic X-ray Experiment, HEAO A -2. The A-2 experiment
consisted of six collimated detectors of thin window X-ray
proportional counters, electronics, and a gas system. The major
purpose of the experiment was to measure the emission and absorption
of cosmic X-rays in the energy range of 0.2 to 60 kiloelectron volts.
Principal Investigators were Elihu Boldt of Goddard Space Flight
Center and Gordon Garmire of Pennsylvania State University. Hardware
was produced by Goddard. Others assisting in the program were the
Bendix Corporation, the University of California, and the California
Institute of Technology.
