Abstract:
This paper discusses RF cavities loaded with dielectric material that could be used in various muon collider facilities. Most of the existing pill-box cavity designs are too large in diameter to fit efficiently in the current cooling lattice designs. The paper describes novel compact dielectric loaded RF cavities designs that fit efficiently in muon cooling lattices and allow multi-frequency cavity designs in the same size cavity by changing the dielectric constant or size. The paper describes the designs of 400 and 800 MHz cavities for the (HCC) helical cooling channel. In addition to the use of the dielectric to reduce the radial size of gas-filled cavities in helical cooling channels, dielectric-loading has the potential use in vacuum cavities for suppression of dark current emission. Cavities that can be used for the phase rotation channel in the front end of a muon collider or neutrino factory are also presented.
