[0002] Microwave vacuum devices usually consist of five parts: electron gun, slow wave structure, energy transmission structure, collector and magnetic system. Among them, the electron gun emits a stable electron flow; the slow wave structure provides space for microwave and electron beam interaction; the energy transmission structure can efficiently transmit microwave signals; the collector recycles electrons; the stable magnetic field provided by the magnetic system can effectively constrain the electron flow emitted by the electron gun, so that it passes through the slow wave structure along the specified route, and fully interacts with the beam wave, thereby improving the working efficiency of the device. It can be seen that the magnetic system plays a vital role in microwave vacuum devices.

[0003] With the development of the industry, more and more high-intensity magnetic fields are used in microwave vacuum devices. The strong magnetic force generated by the magnetic field makes the debugging and installation of vacuum devices more difficult and is accompanied by certain safety risks. Therefore, it is very important to install the vacuum devices in the appropriate position of the magnetic system.
