Problems solved by technology

In addition, the coupling hole is also a through hole formed by first completing the processing of the main acceleration cavity and then hollowing out the side cavity in reverse. Therefore, the edge of the coupling hole produced by this processing method always has sharp corners. This type of structure The coupling hole will cause different degrees of microwave sparking problems in the later stage of the accelerating tube, which seriously restricts the operation stability of the accelerating tube
In addition, for some accelerated cavity structures with special requirements (such as reentrant side cavity structures, etc.), the current machining is difficult to complete, and it will be completed by means of deep drawing forming or casting forming, but this forming technology will be more Complex and low yield in the area of ​​accelerator tube production

Abstract

The invention provides an edge coupling standing wave accelerating tube manufacture method, and relates to the field of medical electron linear accelerators. The invention provides an edge coupling standing wave accelerating tube manufacture method which has the advantages of simple manufacture process and high operating stability of a manufactured accelerating tube, and an edge coupling standing wave accelerating tube. The edge coupling standing wave accelerating tube has a main accelerating chamber without weld joints, has the chamber body with low ignition risk, and is not limited by machining molding conditions. The edge coupling standing wave accelerating tube manufacture method provided by the invention has the advantages that an integrally formed single-cycle accelerating chamber body unit is manufactured through a 3D printing technology; a first time of heating is carried out on the printed single-cycle accelerating chamber body unit; the single-cycle accelerating chamber body unit is mechanically ground and polished through a grinding material; the mechanically ground and polished single-cycle accelerating chamber body unit is cleaned; and the cleaned single-cycle accelerating chamber body unit is assembled to form the edge coupling standing wave accelerating tube.

Description

technical field [0001] The invention relates to the field of medical electron linear accelerators, in particular to a manufacturing method of a side-coupling standing wave accelerating tube and a side-coupling standing wave accelerating tube. Background technique [0002] The accelerator tube is a key component of a medical electron linear accelerator, and its function is to generate high-energy rays for clinical cancer treatment and imaging. At present, many manufacturers of medical electron accelerator tubes are using the side-coupled standing wave accelerator tube structure. The side-coupled cavity is set on both sides of the acceleration path. The electrons provided by the electron gun obtain energy under the action of the microwave field in the main acceleration cavity, and pass The beam hole in the center of the accelerating cavity reaches the outlet of the accelerating tube, while the microwave power in it is coupled and transmitted through the coupling hole between t...
