SRF型腔的铌-钛电子束焊接

Niobium to Titanium Electron Beam Welding for SRF Cavities

M. Parise, D. Passarelli, J. Bernardini

摘要:

钛和铌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连接,在中间使用第三种材料。这种贡献的重点是一种创新的电子束焊接技术的发展,能够产生这两种不同的材料之间的强有力的债券。生产并测试了几个样品,以评估在室温和低温下的机械强度以及所得焊接接头的组成。此外,质子改进计划-II(PIP-II [1])的第一个单辐谐振器2型(SSR 2)腔体单元已经制造,直接将各种等级的钛与铌连接起来,并将报告通过制造收集的结果。

英文摘要:

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.
