Research Abstract	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.
