Problems solved by technology

[0003] Half of the field in the coupling cavity is the standing wave field and the other half is the traveling wave field. During operation, due to the high loss, the heat generation is large, which will easily cause the cavity temperature of the coupling cavity to change, and then the frequency of the coupling cavity will shift. The feeding of the microwave power and the establishment of the accelerating field are affected, so that the beam quality and parameter indicators cannot meet the requirements

Abstract

The invention discloses a coupling cavity device which comprises a coupling cavity and a cooling structure, wherein the cooling structure and the coupling cavity are in butt joint along the axis of the coupling cavity. According to the technical scheme, the cooling structure is in butt joint with the coupling cavity along the axis of the coupling cavity, so that the coupling cavity is cooled, and the operation stability of the coupling cavity under higher power is met.

Description

technical field [0001] The invention relates to the technical field of the accelerator field, in particular to a radio frequency accelerator and a coupling cavity device thereof. Background technique [0002] Radio frequency accelerators are generally used to establish microwave acceleration fields in accelerating structures to accelerate charged particles to higher energies. Among them, the microwave electric field can be generated by the microwave source and transmitted to the coupling cavity through the transmission waveguide. After the microwave field mode is converted by the coupling cavity, it enters the accelerating cavity chain to establish an accelerating field that meets the requirements. [0003] Half of the field in the coupling cavity is the standing wave field and the other half is the traveling wave field. During operation, due to the high loss, the heat generation is large, which will easily cause the cavity temperature of the coupling cavity to change, and t...
