Description

Technical Field

[0001] This utility model relates to the field of electron accelerator technology, specifically to an acceleration tube structure for an electron accelerator. Background Technology

[0002] As an important piece of equipment in fields such as high-energy physics research and materials science, the design of the core component of an electron accelerator, the accelerating tube, directly affects the performance of the accelerator. Although traditional accelerating tube structures can meet acceleration requirements to a certain extent, there is still room for improvement in terms of the uniformity of electric field distribution and energy density. Therefore, developing a new accelerating tube structure to optimize electric field distribution and improve acceleration efficiency is an urgent problem to be solved in the field of electron accelerator technology.

[0003] Referring to the observable accelerating tube of an electron accelerator with reference announcement number CN219145697U, it includes an upper vacuum flange and a lower vacuum flange, with a tube body disposed between the upper and lower vacuum flanges. The tube body includes electrode plates and ceramic rings, which are connected by bonding or brazing and are stacked alternately. Ceramic rings are respectively disposed at both ends of the tube body. The upper and lower vacuum flanges are connected to the tube body through the ceramic rings. This accelerating tube structure, under the action of the ceramic rings and the arc-shaped protrusions on their outer walls, facilitates the creep between the electrode plates. The increased electrical distance also improves the structural strength of the ceramic ring to a certain extent, ensuring its quality. Furthermore, it enhances the mechanical strength of the device, guaranteeing the efficiency and quality of the accelerator tube, extending its service life, and reducing creepage. As can be seen from the above, while this accelerator tube structure can be well applied, it is typically installed using flanges. This requires matching flanges on the external pipeline for installation, making the installation process somewhat inconvenient and frequently causing problems for users. Utility Model Content
