Abstract

The invention discloses a side coupling cavity measuring device for a coupling cavity acceleration structure. The side coupling cavity measuring device comprises a network analyzer, a measuring part and a cable. The measuring part comprises a main body and a coaxial line; the main body is a copper pipe in which a groove is formed; a magnetic coupling ring is arranged at one end of the coaxial line; the coaxial line is located in the main body, and the magnetic coupling ring is located in the groove; the other end of the coaxial line is provided with a coaxial radio frequency connector; the coaxial radio frequency connector is connected with the network analyzer through the cable. According to the technical scheme, through the groove in the main body and the magnetic coupling ring located in the groove, complete short circuit of the acceleration cavities at the two sides of the side coupling cavity to be tested can be achieved, space can be reserved for microwave signal excitation and receiving devices, and therefore the test result of the edge coupling cavity can be accurately obtained.

Description

technical field [0001] The invention relates to the technical field of accelerators, in particular to a side-coupled cavity measurement device and a side-coupled cavity measurement method for a coupled-cavity acceleration structure. Background technique [0002] The coupled cavity accelerating structure is a proton linear accelerator, which is used to accelerate proton beams from tens of MeV to hundreds of MeV energies. A coupled-cavity accelerating structure generally includes multiple accelerating cavities, side-coupled cavities, bridge couplers and end-coupled cavities. In the coupled cavity accelerating structure, two adjacent accelerating cavities are connected through a side coupled cavity. In order to allow the microwave to enter each accelerating cavity through the transmission of the side coupling cavity and establish the designed accelerating electric field in each accelerating cavity, the parameters such as the cavity frequency of the accelerating cavity and the ...
