The application research on the current-type pulse technique to measure ms-scale pulsed neutron time spectrum

It introduces a type of ms-scale pulsed neutron's generation background, radiation characteristics and detection difficulties. It brings forth the method of current-type pulse technique to measure accurately the pulsed neutron time spectrum. It gropes the way to apply the method measuring fusion neutron time of flight spectrum on steady X-ray machine and also testifies the feasibility on the pulsed reactor. The results show that the pulsed neutron time spectrum measurement precision adopting the current-type pulse technique can reach ns scale best.
