Description
Time of flight neutron spectrometry requires for high detection efficiency. In this work we present a detector which is based on a neutron-gamma converter ($^{10}$B disk) followed by a gamma detector (BaF$_2$). The response function to convert time of flight spectrum to energy one was constructed. About four times higher efficiency, compared to an equal thickness $^{6}$Li-doped typically-used neutron detector is predicted. The well-known $^{7}$Li(p,n)$^{7}$Be reaction is used to compare the calculated detector response with the measured one. The low energy tail of the neutron spectrum is well reproduced.
