我们报告了腐蚀站的设计和组装，使质子同时照射金属表面，也接触到熔融铅铋共晶（LBE）。该能力已经在洛斯阿拉莫斯国家实验室（LANL）的离子束材料实验室建立。工程设计的重点是LBE的温度和氧含量控制，以及在辐照活动期间接触区域达到明显超过1dpa的剂量的能力。在本文报道的初步性能演示中，HT9钢制成的样品在450°C下与LBE接触，并在平均质子束电流0.3μA/mm2下照射58h。SRIM[1]计算表明，名义表面剂量范围约为3-22dpa。本文概述了实验设置和设计约束。样品的表征将在随后的论文中报告。
We report the design and assembly of a corrosion station to enable simultaneous proton irradiation of a metallic surface that was also in contact with molten lead–bismuth eutectic (LBE). The capability has been established at the ion beam materials laboratory at Los Alamos National Laboratory (LANL). The engineering design focused on temperature and oxygen content control in the LBE, as well as the ability to achieve doses significantly in excess of 1dpa in the contact region over the irradiation campaigns. In the preliminary demonstration of capability reported here, a sample made of HT9 steel was placed in contact with LBE at 450°C and irradiated for 58h at an average proton beam current of 0.3μA/mm2. SRIM [1] calculations indicate that the nominal surface dose ranged from approximately 3–22dpa. This paper outlines the experimental setup and design constraints. Characterization of the sample will be reported in a subsequent paper.
