Abstract

Fol­low­ing en­cour­ag­ing re­sults with Nb3Sn-coated R&D cav­i­ties, the ex­ist­ing coat­ing sys­tem was up­graded to allow for Nb3Sn coat­ing of CEBAF ac­cel­er­a­tor cav­i­ties. The up­grade was de­signed to allow Nb₃Sn coat­ing of orig­i­nal CEBAF 5-cell cav­i­ties with the vapor dif­fu­sion tech­nique. Sev­eral CEBAF cav­i­ties were coated in the up­graded sys­tem to in­ves­ti­gate vapor dif­fu­sion coat­ings on ex­tended struc­tures. Wit­ness sam­ples coated along with the cav­i­ties were char­ac­ter­ized with ma­te­r­ial sci­ence tech­niques, while coated cav­i­ties were mea­sured at 4 and 2 K. The progress, lessons learned, and the path­for­ward are dis­cussed.
