论文摘要
钛和niobium是用于制造超导射频（SRF）腔的主要材料。这两种金属通常使用各种焊接技术在两者之间使用各种焊接技术。这项贡献着重于开发创新的电子束焊接技术，能够在这两种不同的材料之间产生牢固的键。生产并测试了几个样品，以评估房间和低温温度的机械强度以及所得焊接接头的组成。此外，单辐谐振器的第一个单元2型2型（SSR2）腔，用于质子改进计划-II（PIP-II [1]），已被制造，直接将各种等级的钛与Niobium连接在一起，并将报告通过制造收集的结果。
Titanium and niobium are the main materials used for the fabrication of Superconducting Radio Frequency (SRF) cavities. These two metals are usually joined , using various welding techniques, using a third material in between. This contribution focuses on the development of an innovative electron beam welding technique capable of producing a strong bond between these two different materials. Several samples are produced and tested to assess the mechanical strength at room and cryogenic temperature as well as the composition of the resulting welded joint. Also, the first units of the Single Spoke Resonator type 2 (SSR2) cavities for the Proton Improvement Plan-II (PIP-II [1]) have been fabricated joining directly various grades of titanium to niobium and results gathered through the fabrication will be reported.
