Measurement of neutron and gamma-ray yields from thick targets bombarded by 9 MeV deuterons for the design of deuteron accelerator neutron source

Abstract

  For the design of an intensive neutron source driven by deuteron accelerator, it is necessary to estimate accurately neutron and gamma-ray yields from neutron converter and structure materials based on experimental data. However, the data are not currently sufficient. Under this situation, we have measured systematically double-differential thick target neutron and gamma-ray yields for C, Al, Ti, Cu, Nb and Ta targets at two deuteron energies of 5 and 9 MeV using an NE213 liquid organic scintillator at the Kyushu University Tandem Accelerator Laboratory. We report on the results of systematic analyses for the experimental data of 9MeV incidence and the comparison PHITS calculation.
