Gyrotron traveling wave amplifier with a helical interaction waveguide
Gregory G. Denisov,V. L. Bratman,Adrian W. Cross,Wenlong He,Alan D. R. Phelps,Kevin Ronald,Sergey V. Samsonov,Colin G. Whyte +7 more
TL;DR: In this article, a cylindrical waveguide with a helical corrugation of the inner surface is proposed for a gyrotron traveling wave tube (gyro-TWT).
Journal ArticleDOI
High-gain wide-band gyrotron traveling wave amplifier with a helically corrugated waveguide
V. L. Bratman,Adrian W. Cross,Gregory G. Denisov,Wenlong He,Alan D. R. Phelps,Kevin Ronald,Sergey V. Samsonov,Colin G. Whyte,A. R. Young +8 more
TL;DR: The coupling between the second harmonic cyclotron mode of a gyrating electron beam and the radiation field occurred in the region of near infinite phase velocity over a broad bandwidth by using a cylindrical waveguide with a helical corrugation on its internal surface.
Journal ArticleDOI
Gyro-TWT with a helical operating waveguide: new possibilities to enhance efficiency and frequency bandwidth
TL;DR: In this article, a helical waveguide is used as an operating section of a gyrotron traveling wave tube (gyro-TWT) for a very broad frequency band.
