Optimization of a method of electron-beam welding of niobium resonators
Весці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2016 The review of published data on the modes of EBW of high-purity niobium for SRF resonators was done. Relations between EBW parameters and geometries of welds of niobium sheets 1.7 mm thick are investigated. The optimal modes setting EBW have been used in
