Magnetron, also known as microwave generator, magnetron microwave tube, is a kind of electronic tube, mainly composed of two parts: tube core and magnet. The tube core is composed of a filament, a cathode, an anode and a microwave energy output device. The filament, made of thoriated tungsten wire (ThO2 wire) or pure tungsten wire wound into a spiral shape, is used to heat the cathode. In order to improve the stability of magnetron emission, it is required to carbonize…
