New technical solution for using the time-of-flight technique to measure neutron spectra.

New technical solution is proposed for using the time-of-flight technique to measure neutron spectra on VITA-facility. During 200 ns the energy of protons increases from 1.865 up to 1.915 MeV by supplying the square pulse of 50 kV on the neutron-generating target, which is isolated from facility body. During these 200 ns the generation of neutrons is performed. The spectrum can be obtained measuring the time of flight by a remote neutron detector. Copyright Â
