针对未来先进核能装置候选结构材料在高温和应力等条件下抗辐照性能的评价与快速筛选的需求,基于兰州重离子研究装置( HIRFL )可提供的离子束流条件,设计制作了国内第一套高温应力材料载能离子辐照装置.该装置由束流扫描及探测系统、高温系统、应力系统、真空冷却系统和远程控制系统等5部分组成,可以同时提供高温和拉/压应力下材料的离子束均匀辐照条件,温区覆盖了室温至1200°C范围,拉/压应力范围为0～1176 N,x-y方向均匀扫描面积可大于40 mm×40 mm.利用该装置,已经成功进行了多次高温和应力条件下载能离子辐照先进核能装置候选材料的实验研究,并取得了初步成果.
In order to expedite the evaluation of properties of irradiated materials and the selection of candidate ma-terials for future nuclear energy systems, we developed a specific ion irradiation equipment installed on the Heavy Ion Research Facility of Lanzhou ( HIRFL ) for materials under high temperature and stress. This equipment consists of ion beam scanning and detector system, high temperature load system, stress load system, water cooling system as well as telecommunication and control system. It can supply a wide range of temperature (from room temperature to 1 200 °C ) and stress ( pull/push from 0 to 1 176 N ) simultaneously for materials under ion irradiation. The x-y scanning area with high uniformity is larger than 40 mm×40 mm. This is the first suit of ion irradiation equipment made in China that can be used to study co-operating effects of high temperature and stress in an irradiated material. It has been successfully used several times for materials irradiations under high temperatures and stress, which proved that the new equipment has very good performances in experiments.
