Journal ArticleDOI
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
High Power Wideband Gyrotron Backward Wave Oscillator Operating towards the Terahertz Region
TL;DR: The gyro-BWO generated a maximum output power of 12 kW when driven by a 40 kV, 1.5 A, annular-shaped large-orbit electron beam and achieved a frequency tuning band of 88-102 by adjusting the cavity magnetic field.
Journal ArticleDOI
A cusp electron gun for millimeter wave gyrodevices
Craig R. Donaldson,Wenlong He,Adrian W. Cross,Fengping Li,Alan D. R. Phelps,Lei Zhang,Kevin Ronald,Craig Robertson,Colin G. Whyte,A. R. Young +9 more
TL;DR: In this paper, the experimental results of a thermionic cusp electron gun, used to drive millimeter and submillimeter wave harmonic gyrodevices, were reported using a "smooth" magnetic field reversal formed by two coils.
Journal ArticleDOI
Helically corrugated waveguide gyrotron traveling wave amplifier using a thermionic cathode electron gun
Adrian W. Cross,Wenlong He,Alan D. R. Phelps,Kevin Ronald,Colin G. Whyte,A. R. Young,Craig Robertson,E.G. Rafferty,J. Thomson +8 more
TL;DR: In this paper, an experimental operation of a gyrotron traveling wave amplifier with a helically corrugated waveguide using a thermionic cathode electron gun was presented, where the coupling between the second harmonic cyclotron mode of the gyrating electron beam and the radiation occurred in the region of near infinite phase velocity over a broad frequency band.
