Problems solved by technology
[0006] Existing side-coupled acceleration tubes usually use the method of direct connection between the accelerating cavity and the side-coupling cavity. The adjustment of the operating frequency of the cavity and the interaction between the coupling degree of the accelerating cavity and the coupling cavity will bring great benefits to processing and debugging. Inconvenient, especially for cavity debugging, the frequency of the accelerating cavity and side-coupled cavity and the inter-cavity coupling coefficient will be affected at the same time, making the adjustment more difficult; and in clinical use, the frequency changes of the two accelerating cavities affect each other, which will Leading to unstable working state of medical electron linear accelerator

The invention provides an edge coupling standing wave accelerating tube which comprises a main cavity chain. The main cavity chain is formed by sequentially arranging a number of accelerating cavities of a coaxial line along an axial direction. A beam channel passing through the accelerating cavities are arranged on the axial line. An edge coupling cavity is arranged between two adjacent accelerating cavities, and two connecting ends of the edge coupling cavity are respectively connected with adjacent accelerating cavities through an isolation coupling hole. According to the invention, the accelerating cavities and the edge coupling cavities are separated from each other through the arrangement of the isolation coupling holes, so that the working frequency of the accelerating cavities and the edge coupling cavities can be adjusted separately; the edge coupling standing wave accelerating tube has the advantages of easy tuning and high working stability; and the quality of the generated beam is better.
Description
technical field [0001] The present application relates to the field of medical equipment, in particular to an edge-coupled standing wave accelerator tube and a standing wave accelerator. Background technique [0002] Medical electron linear accelerator is a large medical equipment widely used in radiation therapy of malignant tumors. The medical electron linear accelerator produces high-energy electron beams, bombards metal targets, generates X-rays, irradiates tumor cells, and realizes radiation therapy for malignant tumors. [0003] Accelerating tubes are key components of medical electron linear accelerators. One end of the accelerating tube can be coupled with the electron gun that generates the electron beam, and the other end can be coupled with the target assembly, which accelerates the electrons injected from the electron gun to high energy under the action of microwave electric field, and finally hits the target to generate high-energy X-rays. [0004] According t...
