Description
Nb3Sn is a material with about twice the superheating field and superconducting transition temperature of Nb. By forming an Nb3Sn film on the inner surface of an Nb cavity, the cavity length can be shortened and the system can be operated with a small refrigerator, thus realizing a compact superconducting accelerator system with low operating cost and low price. At KEK, the electroplating method is being investigated as an alternative to the conventional method for forming Nb3Sn films. Based on this research, we have been studying the formation of Nb3Sn films in 3GHz single-cell cavities as our ultimate goal. In this presentation, we will report on the Nb3Sn film formation process and the evaluation results of the fabricated samples.
