Title: Photonic band gap accelerator

Abstract

A preferred compact particle accelerator can include a cell arranged along a longitudinal axis along which a particle beam is accelerated. The preferred cell can include a first plate disposed substantially orthogonal to the longitudinal axis and a second plate disposed substantially parallel to the first plate. The preferred cell can also include a first set of rods connecting the first plate to the second plate and disposed at a first radius about the longitudinal axis. Preferably, the first set of rods each defines an elliptical cross section. The preferred cell can also include a second set of rods connecting the first plate to the second plate and each disposed at least at a second radius greater than the first radius. Optimized geometry of the elliptical rods and the periodicity of the rods in the lattice provide improved wakefield suppression and allow for significant gains in frequency and output.
