Directional Neutron Detector for Rocket and Satellite Experiments
A directional neutron detector for the energy range 1.5 to 15 MeV was constructed. Its design is rugged enough to operate while under high mechanical stress, and at extremes of temperature. The detector is a liquid scintillator using glass capillary tubes to collimate proton recoils from elastic scattering of neutrons in the liquid. Gamma-rays are rejected by pulse shape discrimination, using a special circuit developed for space applications and described by R. A. Tietsch and E. M. Kellogg elsewhere at this symposium.
