This project will further develop the process of electromagnetically forming a niobium radio frequency (RF) superconducting cavity for nuclear physics accelerators. This process eliminates costly machining and electron beam welding and improves performance characteristics. Phase I will determine the power required in the magnetic coils, as well as the arrangement of the coils to the work piece and mandrel, using finite element analysis. An axisymmetric transient magnetic model will determine eddy currents, power loss due to the eddy currents, and induced magnetic forces in the niobium work piece, all as a function of time. This data will be utilized in a detailed design of the tooling required to electromagnetically form a complete RF superconducting cavity. The Phase II project will manufacture and test a single cell niobium RF superconducting cavity.

Commercial Applications and Other Benefits as described by the awardee: Niobium exhibits superconductivity, that is, the lack of electrical resistance at very low temperatures. As a result, superconducting niobium forming should be useful in electron beam accelerators, power generation, propulsion, and other electronic devices.
