Application of rf superconductivity to high-brightness ion beam accelerators

A development program is underway to apply rf superconductivity to the design of cw linear accelerators for high-brightness ion beams. The key issues associated with this endeavor have been delineated in an earlier paper, Considerable progress has been made both experimentally and theoretically to resolve a number of these issues. In this paper the authors summarize this progress. They also identify current and future work in the areas of accelerator technology and superconducting materials which will confront the remaining issues and/or provide added capability to the technology
