论文摘要
用10-30 MEV质子对材料的大量辐照有望提高裂变和融合发电厂的辐射损害。现在可以将中间能量质子束用于大学规模实验室内的材料辐射。本文描述了第一个这样的设施，其中一个Ionetix Ion-12Sc回旋子产生了12 MEV质子束。样品是毫米尺度的拉伸标本，厚度最大为300 um，安装在冷却的束目标上，并控制温度。在高温（500°C）和/或真空下进行放射性标本的专门拉伸测试仪代表裂变和融合系统的条件，而数字图像相关系统则远程测量应变。总体而言，该设施提供了大学规模的辐照和测试能力，并具有中间能量质子，以补充传统的核内裂变反应器和微尺度离子照射。该设施表明，块状质子辐照是核材料研究，下调和资格的可扩展有效方法。
The bulk irradiation of materials with 10-30 MeV protons promises to advance the study of radiation damage for fission and fusion power plants. Intermediate energy proton beams can now be dedicated to materials irradiation within university-scale laboratories. This paper describes the first such facility, with an Ionetix ION-12SC cyclotron producing 12 MeV proton beams. Samples are mm-scale tensile specimens with thicknesses up to 300 um, mounted to a cooled beam target with control over temperature. A specialized tensile tester for radioactive specimens at high temperature (500+ °C) and/or vacuum represents the conditions in fission and fusion systems, while a digital image correlation system remotely measures strain. Overall, the facility provides university-scale irradiation and testing capability with intermediate energy protons to complement traditional in-core fission reactor and micro-scale ion irradiation. This facility demonstrates that bulk proton irradiation is a scalable and effective approach for nuclear materials research, down-selection, and qualification.
