| Title | Nb3Sn Coating of Twin Axis Cavity for Accelerator Applications | ||||
| Abstract | A Superconducting twin axis cavity consisting of a modi-fied cell with two identical beam pipes that can accelerate and decelerate beams within the same structure has been proposed for the Energy Recovery Linac (ERL) applica-tions. Two niobium twin axis cavities fabricated at JLab are processed to deposit the Nb3Sn layer inside using the vapor diffusion method for the first time. Nb3Sn is a po-tential alternative material for replacing Nb in SRF cavi-ties for better performance and reducing operational costs of the accelerators. Because of advanced geometry, larger surface area, increased number of ports and hard to reach areas of the twin axis cavities, the usual coating approach developed for typical elliptical single-axis cavi-ties must be evaluated and requires to be adjusted. In this contribution, we report the first results from the coating of a twin axis cavity and discuss current challenges with an outlook for the future. | ||||
