Abstract

The embodiment of the invention discloses a standing wave accelerating tube and an accelerating device. The standing wave accelerating tube comprises a first body with a beam bunching structure, a second body, a waveguide, a bridge type coupler, an energy switch, a beam tube and a first focusing coil, wherein the second body is provided with a plurality of first side coupling cavities and a plurality of acceleration cavities distributed in the axial direction, and one first side coupling cavity is coupled with two adjacent acceleration cavities; the bridge type coupler is configured to distribute the radio frequency power fed by the waveguide into the beam bunching structure and the accelerating cavity; the energy switch is arranged on the bridge type coupler and can weaken or disappear the acceleration effect of the acceleration cavity; two ends of the beam tube are respectively communicated with the accelerating cavity at the first position and the beam bunching structure; and the first focusing coil is arranged on the beam tube. The standing wave accelerating tube and the accelerating device provided by the embodiment of the invention have the advantages that the keV-level particle beam and the MeV-level particle beam can be output, the low-energy ray dosage rate is improved, and the space occupation volume is reduced.

Description

technical field [0001] The present application relates to the technical field of accelerators, in particular to a standing wave accelerating tube and an accelerating device. Background technique [0002] In the prior art, electron linear accelerators can be divided into traveling wave accelerating tubes and standing wave accelerating tubes. The acceleration efficiency of standing wave accelerating tubes is generally higher than that of traveling wave accelerating tubes. The medical electron linear accelerator is currently the main equipment for radiotherapy, and the acceleration tube is the core component. Usually, the standing wave accelerator tube is used to accelerate the electrons to the required energy, and then output the radiation for treatment. During clinical treatment, the patient needs to be positioned first to verify the treatment plan. Generally, keV-level rays are used for imaging first, and then MeV-level rays are used for treatment. At present, most medical ...
