PERFORMANCE OF THE HIGH-POWER 7-GHZ MAGNICON AMPLIFIER

A new microwave amplifier - the magnicon, in which the beam is modulat ed by varying its spatial position by means of circular deflection is concerned in this paper. The presented device version was developed as a prototype of a microwave power source for linear colliders and it i s an amplifier operating in a frequency-doubling mode. The tube design , the problems faced and overcome during investigation as well as the latest experimental results in which a power of 30 MW, efficiency of 3 5% and pulse width of 0.7 mu s have been obtained at operating frequen cy of 7 GHz are described in the paper.
