Abstract
Westinghouse Electric Corp., Pittsburgh, Pa. SOLID STATE JUNCTION FAST NEUTRON SPECTROMETERS, by R. V. Babcock, J. D. Reichert, and S. L. Ruby. Aug 61, 107p. incl. illus. 27 refs. (Contract AF 29(601)2770, Proj. 8802) (AFSWC TR 61-57)Unclassified report DESCRIPTORS: (*Semiconductors, Solids, *Lithium compounds, Fluorides, *Neutron counters, Neutron flux density, Fast neutrons.) (Thorium, Uranium, Radioactive isotopes.) (*Neutron cross sections, Spectrographic analysis, Instrumentation, Nuclear reactions.) (Carbon, Recoil atom.) Possible fast neutron spectroscopy systems using P-N junctions were investigated. Combinations of fast fission threshold counters exhibited useful energy dependencies. As part of this evaluation, fission cross sections of Th-232 and U-234 in the 12 to 18 Mev range were measured. Li-6F spectrometers exhibited excellent energy resolution. To extend their value, the Li-6(n,alpha)H-3 cross section was measured in the range 0.75 to 1.65 Mev. A carbon recoil method for large neutron fluxes also showed promise. A system using the Li-6F device in the range 0 to 8 Mev and carbon recoil at higher energies is recommended. Where less resolution is needed the fast fission system is more sensitive. (Author)
