Studies were carried out on optimized design of accelerator target for a small size neutron source. Following results were obtained : Neutron yield by using a Lithium target was higher than that using a Beryllium target. The liquid Lithium target was considered since solid Lithium was not suitable for the target due to gas production. The liquid Lithium layer thicker than 70μm was required for a 2.5MeV proton beam. A role-up method by a disk was proposed and the layer around 300μm could be formed.

对小型中子源加速器靶的优化设计进行了研究。结果表明：锂靶的中子产额高于铍靶。考虑液体锂靶，因为固体锂由于气体产生而不适合靶。对于2.5MeV质子束流，要求液态锂层厚度大于70μm。提出了一种圆盘卷取法，可形成300μm左右的薄膜层。
