Abstract

An overmoded accelerator structure is proposed based on a dielectric photonic-band-gap (PBG) disk-loaded structure. The structure consists of dielectric rods and metal disks with irises. It is advantageous for application in high frequency (17 GHz and higher) linacs because of the large dimensions of the structure. The operating mode is a higher-order TM₀₂ mode. One unique feature is that the fundamental TM₀₁ mode is not supported by the structure. Along with that, the dipole mode TM₁₁ is strongly suppressed. The dielectric PBG structure can also be attractive for application in a dielectric wakefield accelerator.
