Abstract

In this study, a theoretical model is proposed to investigate the maximal yield of D–D and D–T neutron tubes. The relationship between the accelerating voltage and the maximal yield is obtained and shows that for a fixed accelerating voltage, the maximal yield only depends on the target current. A concise method is presented to calculate the ion species fraction of the target current from the measured neutron yield. Three neutron tubes were used to experimentally test the method. The calculated percentage of D₂⁺ and D⁺ ions in the target current are ≈94% and ≈6%, respectively, and were found to be in good agreement with experimental values obtained by mass spectrometry in other works.
