| Bibliography: | Background： In recent years, the neutron generator based on D-D reaction is widely investigated due to some potential applications and the advantage of the more security without the use of radioactive tritium target and long target lifetime with D ion self-injection effect in target. The accurate measurement of fast neutron yield of the D-D neutron generator is a key problem to be solved. For D-D neutron generator, the associated particle method is possibly one of the most accurate ways for the neutron source strength calibration. Purpose： In order to measure the neutron yield of D-D neutron generator using the associated particle method, the anisotropy correction factor and the yield ratio of neutron and proton need to be calculated. Methods： A method for calculating the anisotropy correction factor and the yield ratio and a computer program based on MATLAB software platform were developed. Results： In this work, the anisotropy correction factors, the yield ratio of neutron and proton and the total correctio |
