HF RESONATOR AND PARTICLE ACCELERATOR WITH HF RESONATOR

摘要

An HF resonator has a cylindrical cavity made of a dielectric material. The cavity includes a first cylindrical portion, a second cylindrical portion, and a dielectric ring that connects the first portion and the second portion. The inner face of the first cylindrical portion has an electrically conductive first inner coating. An inner face of the second cylindrical portion has an electrically conductive second inner coating. An electrically conductive first enclosed coating is arranged between the first cylindrical portion and the dielectric ring. An electrically conductive second enclosed coating is arranged between the second cylindrical portion and the dielectric ring. The first enclosed coating is conductively connected to the first inner coating. The second enclosed coating is conductively connected to the second inner coating. The HF resonator includes a device that is provided for applying a high-frequency electric voltage between the first enclosed coating and the second enclosed coating.
