A COMPARISON OF THE NEUTRON BEAMS FROM A RADIAL BEAM PORT AND FROM THE TANGENTIAL PORT OF THE NRL REACTOR AS SOURCES FOR NEUTRON-CAPTURE GAMMA RAYS

Abstract

IN THE ELECTRON-VOLT REGION OF NEUTRON ENERGIES THE NEUTRON BEAM FROM A RADIAL PORT (the one designated R-3) provides lo -energy capture gamma rays from heavy nuclides which have intensities from 2 to 6 times those given by the beam from the parallel tangential port striking the same target materials. The signal to background ratios are comparable in the two cases for the geometries used. The intensities of high-energy gamma rays in the direct beam from R-3 are from 5 t 10 times that of the sameenergy gamma rays in the tangential beam. (Author)
