基于D-D和D-T反应的紧凑型中子发生器在实时在线中子活化分析、快中子照相、爆炸物检测及其它中子应用领域有广泛的应用前景，而我国在紧凑型中子发生器技术研究方面相对滞后。本项目拟通过内置天线高频（RF）离子源、靶系统等关键技术的研究，研制一台高产额紧凑型中子发生器，使D-D中子产额大于1.0E9 n/s，D-T中子产额大于1.0E11 n/s。另外，针对紧凑型中子发生器靶处于负的高电位端的特殊问题，将通过二次电子抑制、并排除其它粒子的干扰等关键问题研究，发展用于中子产额测量的伴随粒子测量系统，实现高产额紧凑型中子发生器快中子产额的准确测量，使D-D和D-T快中产额测量的不确定度分别达到小于5%和3%。

Compact neutron generator based on D-D and D-T reaction plays an important role in the following potential research fields, such as the real-time neutron activation analysis,fast neutron radiography，the detection of explosive and other neutron application technology .Study on the technology of compact neutron generator is still in the initial stage in China. In this plan, a compact neutron generator with high neutron yield (greater than 1.0e9 n/s for D-D and greater than 1.0e11 n/s for D-T) will be developed by preparing key elements, such as RF ion source with higher D beam, a well cooled target system. In addition, focus on the problem that the target is located at a negative high potential end in the compact neutron generator, an associated particle monitor system will be developed for neutron yield measurement with a high measurement accuracy（the measurement uncertainty: ≤5% for D-D, ≤3% for D-T）
