Abstract

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 correction factors were presented for the thick-target and for 90° associated particle measurement in the deuterons energy region of 20-700keV.

Conclusion:

The uncertainty of the total correction factors (

) comes mainly from the cross section data. The uncertainty of

is estimated to be about 2%.
