Theory of the anisotropic ferrite wake-field accelerator. I. Azimuthally symmetric case

The theory of the anisotropic ferrite wake-field accelerator is solved, wherein the ferrite is driven into saturation by a static magnetic field, resulting in a permeability tensor having off-diagonal elements. We show that it is possible to obtain a maximum accelerating gradient of 1.5 MV/[m (nC driver beam charge)] for a driver beam of 0.7-mm rms bunch length. This compares favorably with wake-field accelerators based upon other types of structures.
