Abstract Ion beams are indispensible for understanding radiation effects in materials, enabling access to conditions challenging to perform with neutrons. However, ion irradiations can produce potential artifacts from beam rastering, high displacement damage rate effective “temperature shifts”, subthreshold collisions, high ionization rates, and non-monoenergetic primary knock-on atom energies. The influence of near-surface denuded zones and implanted ion effects is analyzed, including diffusional broadening effects. At high ion irradiation energies, “swift heavy ion” effects can lead to enhanced defect production or recovery. Ion energies of 10–50 MeV typically offer a good compromise for minimizing near-surface, implanted ion, and swift heavy ion effects.

离子束在辐射效应研究中的机会和限制:弥合带电粒子和中子辐射之间的关键差距

摘要 离子束对于了解材料中的辐射效应是必不可少的,它能够帮助我们进入难以用中子进行的条件。然而,离子辐照可能会产生来自光束光栅、高位移损伤率有效“温度偏移”、亚阈值碰撞、高电离率和非单能初级碰撞原子能量的潜在伪影。分析了近表面裸露区和注入离子效应的影响,包括扩散加宽效应。在高离子辐射能量下,“快速重离子”效应会导致缺陷产生或恢复的增加。10-50 MeV 的离子能量通常为最大限度地减少近表面、注入离子和快速重离子效应提供了一个很好的折衷方案。
