Abstract : A fast neutron sp ctrometer was designed and constructed. The spectrometer uses He3 gas at 1500 psi as the reacting medium for fast neutrons and solid state detectors to detect the product particles. Investigation is made into geometry and materials to use to obtain optimum use of the solid state detectors. A igital computer program is presented to calculate and plot the energy and angular distribution of the products of the reaction. To prepare targets for neutrons production with a Van de Graaff generator, two means of obtaining a thin etallic coating on a target disc are investigated. These are ion sputtering and reduction of a metal from a new metallic compound, Zr(TFA)4. Some experim ntal data is obtained concerning the ion sputtering process. (Author)
