Application of RF superconductivity to a high-current linac
In 1997, Los Alamos National Laboratory (LANL) initiated a development program for high-current, superconducting, proton-linac technology to build prototype components of this linac and demonstrate the feasibility. Seven hundred-MHz niobium cavities with elliptical shapes are being built, as well as power couplers to transfer high RF power to these cavities. The cavities and power couplers will be integrated in cryostats as linac cryomodules. This paper describes the linac design and the status of the development program.
