In order to obtain a fundamental knowledge on the initial processes of displacement damage which cause radiation damage in nuclear materials, an experiment using ion irradiation at low temperature, positron beam and resistivity measurement was carried out. Displacement damage efficiencies were experimentally derived and migration stage of point defects and their clusters were clarified.

为了获得核材料中引起辐射损伤的位移损伤初始过程的基本知识，进行了低温离子辐照、正电子束和电阻率测量实验。实验上推导了位移损伤效率，明确了点缺陷及其团簇的迁移阶段。
