Abstract

The invention discloses a fast joint for compact superconductive cyclotron's high frequency resonator coaxial waveguide. The fast joint comprises an internal conductor and insulation supports. The internal conductor is of a cylindrical shape; the outer side wall of the internal conductor is provided with a middle section as well as spiral joint sections at two sides of the middle section. The outer side walls of the internal conductor among the middle section and the spiral joint sections are provided with two anti-current grooves. A circumferential protrusion part is arranged between the two anti-current grooves. The circumferential side wall of the middle section is provided with three installation holes. Each installation hole is provided with an insulation support. The insertion end of each insulation support is in threaded connection with a spring. The spring is fixedly connected to the installation hole. The outer end of the insulation support undergoes a fillet processing. The two end faces of the middle section are provided with a first step respectively. The outer end faces of the two spiral joint sections are provided with second steps. Simple in structure and small in size, the fast joint enables the convenient and rapid installation, maintenance and replacement of a coaxial waveguide.

Description

technical field [0001] The invention belongs to the quick connection technology in a special environment, and relates to a technology for quick connection of a high-frequency resonant cavity coaxial waveguide, in particular to a quick joint for a compact superconducting cyclotron high-frequency resonant cavity coaxial waveguide , especially the selection of joint material, the design of insulating support and the design of anti-flow groove, can effectively prevent the accident of coaxial line ignition. Background technique [0002] Cyclotrons are widely used in the field of nuclear medicine, especially in the fields of radiopharmaceuticals and tumor treatment. Hefei Ion Beam Medical Center has carried out proton therapy and other related biomedical research work, and has done a lot of research and experiment work on the development of superconducting cyclotron. The host system of the proton cyclotron uses the electric field of the resonant cavity to accelerate ions, and the...
