Electron Beam Welding of Superconducting Cavities Made of Ultra-Pure Niobium
Igar L. Pobal, Siarhei V. Yurevich

Cite as:

Manufacture of superconducting radiofrequency (SRF) cavities for modern accelerators requires ultra-purity niobium. Joining components of such cavities is only possible with the use of electron-beam welding. Investigations ...  read more
