The properties of some new types of beta-ray spectrometers and proton spectrometers for use in space were studied. A laboratory prototype and a light-weight prototype of a high-energy beta-ray spectrometer were constructed. Tests were performed on these spectrometers as well as the high-energy beta-ray spectrometer reported in STLTR-59-0000-09950. Support work included construction and testing of a pulse-height analyzer, a linear pulse amplifier, a nano-second coincidence circuit and gating circuitry for use in conjunction with the spectrometers. A laboratory luminescent chamber was constructed and tested at the California Institute of Technologys synchrotron. The energy of the primary radiation can usually be determined and a lower energy bound is always possible. Immediate applications include the investigation of the primary radiation near the earth with particular emphasis on gamma rays and neutrons, the detection of atomic or thermonuclear space explosions, the identification of hostile satellites, and certain fundamental high-energy physics experiments.
