WebJul 27, 2024 · We describe the design and performance of an Nb 3 Sn coating system that converts the inner surface of niobium cavities to an Nb 3 Sn film. The niobium surface, heated by radiation from the niobium retort, is exposed to Sn and SnCl 2 vapor during the heat cycle, which results in about 2 μ m Nb 3 Sn film on the niobium surface. WebIn this paper , the progress in the development of Nb 3 Sn cavity coating by vapour diffusion method at IMP was reported . T hree 1.3 GHz single cell cavities were coated …
