AbstractTo improve the superconducting components of radio frequency devices used in particle accelerators, there is a need to develop techniques to create a layer of niobium on the interior of a copper elliptical cavity. This project will develop an electrically-mediated electro-deposition process to deposit niobium onto copper elliptical cavities from a room temperature ionic liquid plating bath. Electrical mediation will enhance the electro-deposition process through the control of additional process parameters. In Phase I, a small copper substrate will be coated with niobium and the thickness, uniformity, adhesion, and microstructure of the deposit will be evaluated. In Phase II, a layer of niobium will be deposited onto the interior surface of a copper elliptical cavity, and the performance of the cavity will be evaluated in radio frequency devices. Commercial Applications and other Benefits as described by the awardee An electrically-mediated electro-deposition process would be a simpler, and less expensive method for depositing high purity niobium coatings on superconducting radio frequency cavities. Areas of interest include both the energy and national security industries. Additionally, niobium is a biocompatible material, making niobium coatings a candidate for surgical implants.
