Description

Technical Field

[0001] The utility model relates to the technical field of X-band magnetrons, in particular to an X-band magnetron wiring device. Background Art

[0002] The X-band magnetron is the power source of the electron linear accelerator, providing microwave power. The connection terminals of the X-band magnetron are divided into cathode and filament. When working, the cathode needs to be connected to a high voltage of tens of KV, and the filament needs to be connected to a voltage of about 10V. The electron linear accelerator accelerates electrons to hit the target through microwave power to generate rays for treatment or industrial detection.

[0003] At present, the X-band magnetron used in electron linear accelerators is generally a coaxial X-band magnetron, in which the cathode end and the filament end are coaxially arranged and very close to each other. There is no special terminal for wiring the cathode end and the filament end, and it is impossible to increase the terminal by subsequent welding. This makes wiring inconvenient when using the X-band magnetron, and it is easy to short-circuit or high-voltage wire falls, thereby damaging the X-band magnetron.

[0004] Therefore, how to improve the convenience and reliability of cathode and filament wiring of X-band magnetrons, thereby reducing the probability of high-voltage line dropping and short circuit, is a technical problem that technical personnel in this field urgently need to solve.
