Description

A tin vapor diffusion system was constructed for Nb3Sn cavity R&D at KEK.
After construction of the vapor diffusion system, we have performed Nb3Sn coating test for several samples.
Several samples are observed and we optimized the coating parameter for cavity coating.
After coating Nb3Sn for the single-cell cavity, flux expulsion and cavity performance were measured.
In this presentation, sample coating results and cavity performance results are reported.
