  We present the results of commissioning a dedicated furnace for Nb3Sn
coatings of 2.6 GHz single cell cavities. Nb3Sn is a desired coating due to its
high critical temperature and smaller surface resistance compared to bulk Nb.
Usage of Nb3Sn coated cavities will greatly reduce operating costs due to
decreased dependance on cryo cooling. Tin is deposited by use of a tin chloride
nucleation agent and tin vapor diffusion. Analysis of the resultant coating was
performed using SEM/EDS to verify successful formation of Nb3Sn. Witness
samples in line of sight of the source were used in order to understand the
coating efficacy.
