In order to meet the demand for miniaturized controllable neutron source detection,an optimized design was carried out on the currently in service small deuterium-deuterium pulse neutron generator.The experimental test results show that the optimized neutron generator has a deuterium-deuterium neutron yield greater than 2×106 n/s,a neutron yield stability of 97％,and a lifespan of over 8,000 hours,laying the foundation for the design and application of miniaturized controllable neutron sources.
