Abstract
A planar RF accelerating structure for charged particles preferably wherein the accelerating field is independent of the transverse position of the particle beam. In a first embodiment, the RF structure has a 'tugboat' design to provide a capacitive loading effect; in a second embodiment, the structure has a 'barbell' shape to provide an inductive loading effect. In both configurations, the axial electric field is substantially constant, or assumes a prescribed profile other than the typical half-sine distribution of a conventional rectangular cavity.
