在中国原子能科学研究院已经建成并投入运行的中国先进研究堆(CARR)具有高达1×10~(15)cm~(-2)·s~(-1)中子注量率,将集成~(235)U靶的离子源通过预留的中子管道伸入反应堆高中子注量率区域,可产生强流裂变碎片放射性核束。然而,要实现前述目标,需要解决反应堆中子管道尺寸有限、离子源工作区辐射强等问题。本工作组正在研制一套1:1尺寸的反应堆中子孔道内离子源,研究解决 The China Advanced Research Reactor (CARR), which has been established and put into operation at China Institute of Atomic Energy, has a neutron fluence rate of up to 1 × 10 ~ (15) cm -2 (-2) · s -1, (235) U-target ion source through the reserved neutron pipeline into the reactor high-neutron fluence rate region, can produce strong flow fission fragment radioactive nuclear beam. However, to achieve the aforementioned objectives, there is a need to solve the problems of limited reactor neutron pipelines and strong radiation in the ion source working area. The working group is developing a 1: 1 size reactor neutron hole ion source, to study and solve
