Times Cited Count：0 Percentile：0.00(Nuclear Science & Technology)Spallation neutron at 180 degrees is of important for an evaluation of radiation protection for ADS (Accelerator-Driven System) and the nuclear physics. It was, however, quite difficult to measure it. We measured the energy spectrum of spallation neutron at 180 degrees at the proton transport beam line (3NBT) to MLF (Materials and Life Science Experimental Facility) on J-PARC by the NE213 liquid scintillator. The irradiated proton energy was 3 GeV, and the intensity was 1
10
protons above. The neutron energy was determined by Time-Of-Flight method with n-gamma discrimination. We also simulated the energy spectrum by using PHITS code and compared with measured spectrum. In this paper, the overview of the experiment and the results are described.

The response functions of a BC501A liquid organic scintillator have been measured for incidence of various charged particles to investigate the relationship between the kinetic energy of the charged particles and the light output of BC501A. The experiment was performed at Heavy-Ion Medical Accelerator in Chiba (HIMAC) utilizing spallation reactions by heavy ion bombardment on a graphite target. Charged particles incidental on BC501A were identified with the two-dimensional scatter plot of the time-of-flight and the light output. The light output of the BC501A scintillator was deduced as a function of the kinetic energy of the charged particles, and was compared with the semi-empirical formula. While the experimental data showed a good agreement with the formula for proton and deuteron, the data gave slightly larger values compared with the systematic trend for alpha particle.

A 14 mm diameter spherical NE213 spectrometer has been developed for applying to fusion neutronics experiments. It is used to measure the fast neutron spectra in assemblies of various materials irradiated with 14 MeV neutrons. The characteristics of neutron gamma-ray discrimination was investigated, and it was found that the wall-escape of recoil protons produced in the detector should be treated carefully in the case of a small size detector such as this one. Response matrix for spectrum unfolding has been calculated by a Monte Carlo code. Calculated response for 14 MeV neutrons agreed well with measured one. The present spectrometer was applied to in-system neutrons spectrum measurements in a lithium-oxide assembly bombarded by D-T neutrons. The spectra obtained by unfolding were compared with the results calculated by the neutron transport code DOT3.5, and with reaction rates measured by fission counters and activation detectors. Consequently it has been demonstrated that the spectrometer is very useful for fusion neutronics experiments.
