The electron gun of the electron linear accelerator is the electron source of the accelerator, which provides the main body of the ac...

AI Technical Summary

Problems solved by technology

At present, there is no set of ready-made fixing tools for the assembly and welding of electron guns. The assembly and welding of electron guns is mostly completed on industrial platforms, and the parallelism between the electron gun and the standing wave accelerating tube cavity must be adjusted by a height gauge. In other words, the process is cumbersome, the platform takes a long time, and the efficiency is low. In addition, the parallelism determined by the height gauge has a large error, and it is easy to deform during the welding process and is difficult to grasp.

At present, there are few manufacturers in China that can independently produce accelerating tubes, but accelerating tubes are widely used, and the installation and welding of electron guns is one of the most important procedures, but there is no matching positioning equipment to meet the requirements of electron guns.
