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

Abstract

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.

Deuteron nuclear data for the design of accelerator-based neutron sources: Measurement, model analysis, evaluation, and application

“…We have carried out a series of measurements of doubledifferential neutron yields from thick targets irradiated by deuterons at the Kyushu University Tandem accelerator Laboratory (KUTL) [25][26][27][28][29][30]: carbon, aluminum, titanium, copper, niobium, and tantalum for bombardment energies of 5 and 9 MeV. In addition, double-differential thick target gamma-ray yields from carbon and aluminum irradiated by 5 and 9 MeV deuterons were measured at the same time.…”

“…The details of the experimental set up and procedure have been reported in Refs. [25][26][27][28][29][30].…”

Measurement of Gamma-ray Yield from Thick Carbon Target Irradiated by 5 and 9 MeV Deuterons

“…Howev-JRPR er, they were treated as background events in the neutron data analysis. As far as theoretical models are concerned, it was found that the intra-nuclear cascade of Liege (INCL) model [7] in PHITS [8] generally reproduce the DDTTNYs data of Al targets in both the shape and magnitude [9]. Also, it will be necessary to validate some reaction models used in PHITS using gamma-ray yield data for engineering design of deuteron accelerator facilities.…”
