Low-energy particle production and transport for 200 GeV/ c protons in iron and comparisons with experimental data
Abstract
Calculated results for 200 GeV/ c protons incident on an iron, calorimeter-like, target are presented and compared with experimental data. The calculations were carried out with the hadron transport code HETC88. The quantities that are compared are the production per unit volume of 18F and 24Na in aluminum and the production per unit volume of 115mIn in indium as a function of depth and radius in the target. The production of 24Na and 115mIn is due primarily to the low energy (≤ 20 MeV) neutron flux, and thus the comparisons here test the capability of HETC88 for producing and transporting these low-energy neutrons or more precisely for predicting the flux per unit energy of these low-energy neutrons as a function of depth and radius in the target. The calculated results are in good agreement with the 118F production data (energies ⪆ 40 MeV) and the 24Na production data (energies ⪆ 5 MeV) and in moderate agreement with the 115mIn production data (energies ⪆ 0.4 MeV.)
