抄録

We have investigated the energy response of a 6Li-loaded liquid scintillator to MeV neutrons. It consists of three 6Li-glass scintillator plates inside a liquid organic scintillator BC-501A, which can detect selectively neutrons that lose the full energy in the BC-501A using a coincidence signal generated from the capture event of thermalized neutrons in the 6Li-glass scintillators. The response functions were measured using 4.7, 7.2 and 9.0 MeV monoenergetic neutrons. The measured ones were compared with Monte Carlo calculations performed by combining the neutron transport code PHITS and the scintillator response calculation code SCINFUL. The experimental light output spectra were in good agreement with the calculated ones in shape. The energy dependence of the detection efficiency was reproduced by the calculation.
