SXLS RF cavity and system

The design of a 700 MeV superconducting compact electron storage ring for applied X-ray lithography is in its final stage. This succeeds a 200 MeV warm dipole model constructed and now in operation at Brookhaven National Laboratory (BNL). RF cavities and systems in both machines are discussed. The authors present cavity design parameters, construction, and the kind of mode suppression as well as the type of tuner and input window to provide 300 kV of accelerating voltage at 211.54 MHz. A 65 kW, RF power source is described. >
