英文摘要：

The new fast neutron detector with high time resolution was introduced. Monte Carlo method was used to simulate the energy response of neutron of the detector and calculate its conversion efficiency of proton. The detector possibly has good capability in time resolution according to the result. Using this detector, by measuring the time of flight of neutrons, we can get the energy spectrum of fast neutrons more accurately.
