DESIGN AND CONSTRUCTION OF A FAST NEUTRON SPECTROMETER USING SOLID STATE DETECTORS (thesis)
Technical Report
·
OSTI ID:4732353
A fast neutron spectrometer is designed and constructed. The spectrometer uses He/sup 3/ gas at pressures up to 1500 psi as the reacting medium for fast neutrons and solid state detectors as the means of detecting the product particles of the reaction. An investigation is made into the best geometry and materials to use in order to obtain optimum use of the solid state detectors. A digital computer program is presented to calculate and plot the energy and angular distribution of the products of the reaction. To prepare targets for neutron production with a Van de Graaff generator, two means of obtaining a thin metallic coating on a target disc are investigated. These are ion sputtering and reduction of a metal from a new metallic compound, are completed but no spectroscopic data taken. Use of the computer program provides data with good correlation to that found in the literature. Some experimental data are obtained concerning the ion sputtering process. (auth)
