摘要
A double-beam magnetron injection gun was used to improve the output power of gyrotrons. A double-beam magnetron injection gun can output two relativistic electron beams, which is a better way to raise the current of the magnetron injection gun without reducing the quality of electron beams. Compared with the double-anode magnetron injection gun with the same output current, the double-beam magnetron injection gun can reduce velocity spread and improve the quality of electron beams, because of its smaller influence of the space charge. Using the software MAGIC, a double-beam magnetron injection gun with a modest velocity ratio and a low velocity spread of electron beams was designed.
