Radiation conversion target for neutron source

The invention relates to a radiation conversion target for a neutron source, and belongs to the technical field of neutron physics and neutron sources, the radiation conversion target comprises a target body, the target body is formed by stacking a plurality of target sheets, and a target sheet gap for cooling liquid to circulate exists between every two adjacent target sheets. The cooling liquid can circulate between the adjacent target sheets, and meanwhile, the thicknesses of the target sheets are sequentially changed from thin to thick according to the electron beam energy deposition density change trend in the target body, so that the target sheets with high electron beam energy deposition density are better cooled, the high neutron yield is ensured, heat dissipation of the target body is facilitated, and the purpose of protecting the radiation conversion target is achieved. 本发明涉及一种用于中子源的辐射转化靶，属于中子物理及中子源技术领域，包括靶体，所述靶体由多个靶片堆叠而成，相邻的靶片之间存在供冷却液流通的靶片间隙，本发明中靶体采用多个靶片组成叠片靶结构，冷却液可在相邻的靶片之间流通，同时，按照靶体中电子束能量沉积密度变化趋势，
