| Abstract [eng] |
It is proposed to use the principles of the coaxial and inverted coaxial magnetrons for creation of highly effective crossed – field active coaxial and active inverted coaxial electron guns that not only produce, bunch and inject electron stream into next cascade of the M-type amplifier or frequency transducer, but also ensure high frequency stability, large output signal power and operation at higher temporal harmonics and subharmonics of the input signal. Both magnetron active coaxial and active coaxial inverted electron guns should include a high quality coaxial resonator connected with the slow – wave system operating at π-oscillations but in a first case this resonator covers the slow –wave system and a cathode and in a second one – a large cathode with inner emitting surface covers slow – wave system and stabilizing resonator. Working duration of the devices using such active coaxial magnetron guns should be 3 – 5 times larger in comparison with ordinary magnetron guns because of released thermal regime of operation. The expressions for evaluation of elektronic efficiency and ultimate increase in a gain of the active coaxial magnetron gun are presented. They confirm the high efficiency of the gun. |
