Abstract:
1. An RF resonator cavity for accelerating charged particles, wherein the RF resonator cavity is configured for coupling to an electromagnetic RF field that, during operation, acts on a particle beam which passes through the RF resonator cavity, comprising a plurality of intermediate electrodes arranged in the RF resonator cavity along the beam path of the particle beam and configured to increase the electrical breakdown strength, wherein the plurality of intermediate electrodes are suspended within the RF resonator cavity such that the intermediate electrodes spaced apart from an interior wall of the RF resonator cavity in a radially inward direction, wherein the plurality of intermediate electrodes are moveably mounted with a resilient bearing, and wherein each intermediate electrode has a limited conductivity such that, upon coupling-in of the electromagnetic RF field at operating frequency of the RF resonator cavity, the intermediate electrode is at least partially permeated by the coupled-in electromagnetic RF field.
