Double differential thick target neutron yields from 5and 9 MeV deuteron incidence on aluminum and SUS304st ainless steel were measured at the Kyushu University Tandem Accelerator Laboratory. An aluminum, and a SUS 304 foil which were thick enough for a deuteron to stop in the foils were placed at the center of a vacuum chamber. AnNE213 liquid organic scintillator was employed to detect neutrons emitted from targets. To consider the contribution of scattered neutrons from the floor, we also measured neutron yields with an iron shadow bar located in front of the scintillator. Because incident deuteron beam was not pulsed and the Time-of-Flight method was not applied, the energy spectrum was derived from unfolding the light output spectrum using the FORIST code. The re sponse function of the detector was calculated with the SCINFUL-QMD code. The experimental results were compared with the calculation data of the TALYS and PHITS code, and it turned out that the calculation data does not reproduce the experimental ones satisfactorily.

Double differential neutron yields from carbon target irradiated by 5 MeV and 9 MeV deuterons were measured at the Kyushu University Tandem Accelerator Laboratory. A carbon target was thick enough to stop the incident deuterons in the target. An NE213 liquid organic scintillator was employed to detect neutrons emitted from the target and placed at several directions from 0° to 140°. To estimate the contribution of scattered neutrons from the floor and walls, neutron yields were measured with an iron shadow bar located in front of the scintillator. The measured energy spectrum was derived by an unfolding method with FORIST and MAXED codes using the response functions of the NE213 scintillator calculated with the SCINFUL-QMD code. The incident energy dependence of total thick target neutron yields for carbon was investigated over the energy range from 5 to 50 MeV and the empirical formula was obtained. The measured neutron energy spectra were also compared with the calculations by PHITS code.

Measurement of Double Differential Neutron Yields from Thick Aluminum Target Irradiated by 9 MeV Deuteron

Double differential neutron yields from a thick aluminum target irradiated by 9 MeV deuterons were measured at the Kyushu University Tandem accelerator Laboratory (KUTL). An NE213 liquid organic scintillator (50.4 mm thick and 50.4 mm in diameter) was used as a neutron detector. Neutron yields from the target were measured at nine angles between 0° and 140°. The neutron energy spectra were obtained by means of an unfolding method using FORIST code with the response function of the NE213 scintillator calculated by SCINFUL-QMD code. The experimental result was compared with other measured data at 5 and 40 MeV and the calculation based on intra-nuclear cascade of Liège (INCL) model in PHITS code.
