Nuclear Material Irradiation System of 4.5 MV Electrostatic Accelerator at Peking University

  • 摘要: 随着我国核电事业的发展,新一代核能系统对材料性能的更高要求已经成为材料科学领域新的挑战,为适应这一需求,为高性能抗辐照核材料的研究和测试提供平台,北京大学4.5 MV静电加速器组在核物理与核技术国家重点实验室的支持下,在原有束线基础上新增设质子/氦温控辐照系统并投入使用。该系统可进行能量范围在0:73:5 MeV内的质子或氦离子辐照,离子流强最高10 A,并可进行最高1 000 ℃的加热辐照,特别适合开展核能材料的初级快速筛选。此外,4.5 MV加速器与26 MV串列加速器联合建设的双束共靶辐照系统也已经整体调试完成,可为材料辐照效应的进一步研究提供良好的实验平台.

    Understanding nuclear materials response in extreme environments, such as intense irradiation and high temperature in fusion reactors and advanced fission reactors, is significant in designing advanced nuclear energy systems. Recently, a nuclear material irradiation system has been installed and in service on the beam line of 4.5 MV electrostatic accelerator. The energy range of proton or helium ion accelerated will be from 0.7~3.5 MeV, and the ion current will be up to 10 A.
