Abstract :
The secondary emission magnetron injection gun (SEMIG) is relatively a new cold-cathode electron gun. The advantages of the SEMIG in long pulse operations are more obvious when we apply it for power radio-frequency sources and electron linacs. The experimental facility and a method of emission excitation in the SEMIG are described. The method consists of the secondary emission multiplication on the trailing edge of the voltage pulse. The SEMIG is operated with the external pulse-driver. A similar method is known for magnetrons. The electron beam with pulse duration up to 3000 μs and repetition rate up to 50 Hz (duty factor up to 15%) is obtained
