    Design of a high power, 10 GHz auto-resonant peniotron amplifier
    (1992) Musyoki, Stephen; Sakamoto, Keishi; Watanabe, Akihiko
    The autoresonant peniotron amplifier is a suitable source of high power RF radiation because of its high gain, high power, high frequency and high efficiency operation features. In this report we present our simulation results of a 10 GHz, 2.2 GW autoresonant peniotron amplifier with an electron energy conversion efficiency of 72.5 % and a gain of about 58 dB

    Design of a high power, 2.75 GHz relativistic peniotron oscillator
    (1992-10) Musyoki, Stephen; Sakamoto, Keishi; Watanabe, Akihiko
    In the peniotron oscillator, the kinetic energy of relativistic electrons can be efficiently converted to an electromagnetic wave. This feature makes the peniotron a very attractive source of high power microwaves, which is required in heating of fusion plasma in tokamaks and high gradient particle accelerators. In this report we present the design of a 2.75 GHz relativistic peniotron oscillator which is capable of generating a microwave radiation of 30 megawatt with an efficiency of about 60 %. The experimental test results of the designed cavity are also presented
