High frequency single mode traveling wave structure for particle acceleration

摘要

The development of the new high frequency slow traveling wave structures is one of the promising directions in accomplishment of charged particles high acceleration gradient The disc and dielectric loaded structures are the most known structures with slowly propagating modes. In this paper a large aperture high frequency metallic two-layer accelerating structure is studied. The electrodynamical properties of the slowly propagating TM_(01) mode in a metallic tube with internally coated low conductive thin layer are examined.
