摘　　要：为适应小型化可控中子源检测的需求,将现役的小型氘-氘脉冲中子发生器进行了优化设计。通过实验测试结果表明:经优化设计的中子发生器的氘-氘中子产额大于2×10^(6) n/s,中子产额稳定性达到97%,寿命可达8000 h以上,为小型化可控中子源的设计及应用奠定了基础。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 deuteriumdeuterium neutron yield greater than 2x10°n/s,a neutron yield stability of 97%,and a lifespan of over 8,00o hours,laying the foundation for the design and application of miniaturized controllable neutron sources.
