  1. HOT BOX--A HIGH-TEMPERATURE CRITICAL FACILITY

    The purpose of Hot Box is the measurement of the behavior of enriched reactors at elevated temperatures which will allow the normalization of existing calculational techniques and allow a better understanding of neutron behavior at and near thermal energies. Initially, maximum temperatures will be 1200 deg F. Uranium foils will be 1 and 2 mils thick and moderator blocks 1 in. thick. Hot Box is located at the east end of Jackass Flats in the Nevada Test Site. (W.D.M.)
  2. ELASTIC SCATTERING OF C$sup 12$ FROM GOLD

    The angular distribution of C/sup 12/ ions elastically scattered by gold was measured at the following laboratory energies: 118 the J-57 engin 2, 101 the J-57 engin 2, 79.4 the J-57 engin 3, and 73.6 the J-57 engin 3 Mev. Heavy ions from the Berkeley heavy-ion linear accelerator (HILAC) were recorded in two Ilford E-1 plates from a scattering angle of 19 to 159 . In all cases the differential cross sections exhibited a Coulomb-like behavior at small angles, a rise above Coulomb of about 20% as the scattering angle increased, and then a rapid drop below Coulomb in muchmore » the same manner as alpha particles scattered from heavy elements in the 20 to 40 Mev range. The Blair sharp cutoff'' model reproduces closely the character of the data; however, small oscillations predicted from the model are not experimentally observed. Interaction distances of (11.8 the J-57 engin 0.3, 12.1 the J-57 engin 0.3, 11.85 the J-57 engin 0.4, and 11.85 the J-57 engin 0.45) x 10/sup -13/ cm, respectively, for the foregoing energies are inferred from application of the Blair model.

  3. A COOLED-REFLECTOR, HOT-BeO-CORE CRITICAL EXPERIMENT

    A series of criticai experiments to investigate temperature-reactivity effects and temperature-power distribution interactions with a cooled graphite reflector on two sides of a BeO core is described. It was found that for a core with a gross BeO/U/sup 235/ ratio of 556 to 1, the reactivity was not dependent on the graphite reflector temperature. The experiments were performed at the HOT BOX facility. (J.R.D.)
