  • Design of a high power, 10 GHz auto-resonant peniotron amplifier 
    Musyoki, Stephen; Sakamoto, Keishi; Watanabe, Akihiko (1992)
    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 ...
  • Design of a high power, 2.75 GHz relativistic peniotron oscillator 
    Musyoki, Stephen; Sakamoto, Keishi; Watanabe, Akihiko (1992-10)
    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 ...
  • Emittance measurement of high-brightness microbeams 
    Musyoki, Stephen; Ishizuka, Hiroshi; Nakahara, Yuriko; Kawasaki, Sunao; Shimizu, Hiroshi; Watanabe, Akihiko; Shiho, Makoto (Japanese Journal of Applied Physics, 1994)
    Arrays of microtriodes have recently become available due to the development of microfabricated field-emission electron sources. Computer simulation has shown that the brightness of beams emitted by them is significantly ...
  • A new method of emittance measurement for electron beams from the Micro-emitter 
    Ishizuka, Hiroshi; Nakahara, Yuriko; Kawasaki, Sunao; Musyoki, Stephen; Shimizu, Hiroshi; Watanabe, Akihiko; Shiho, Makoto (1994)
    Recently a new type of cathode called Micor-emitter has been put in progress. This cathode is a microfabricated field emitter having the characteristics of very low emittance and high brightness. We cannot measure the ...
