In the University of Tokyo, X-band electron linac driven neutron source is being developed for measuring cross section of high energy neutrons of nuclear fuel materials.
Focusing on high energy (〜100 keV) neutrons, neutron target and moderator were simulated in order to optimize for short pulse neutron.
From the simulation result, pulse width of 10 – 100 keV neutrons were broadened to 5.8 ns.
