Journal ArticleDOI
Experimental results on microwave pulse compression using helically corrugated waveguide
M. McStravick,Sergey V. Samsonov,Kevin Ronald,Sergey V. Mishakin,Wenlong He,G. G. Denisov,Colin G. Whyte,V. L. Bratman,Adrian W. Cross,A. R. Young,P. MacInnes,Craig Robertson,Alan D. R. Phelps +12 more
TL;DR: In this paper, the authors developed a method to generate ultrahigh-power short-microwave pulses by using a known principle of compression (reduction in pulse duration accompanying with increase in pulse amplitude) of a frequency-swept wave packet propagating through a dispersive medium.
Journal ArticleDOI
Free-electron maser based on a cavity with two- and one-dimensional distributed feedback
Ivan Konoplev,Adrian W. Cross,P. MacInnes,Wenlong He,Alan D. R. Phelps,Colin G. Whyte,Kevin Ronald,Craig Robertson +7 more
TL;DR: In this article, a coaxial free-electron maser based on two-dimensional and one-dimensional distributed feedback, driven by a 70mm diameter, annular electron beam is presented.
Journal ArticleDOI
High-Current Electron Beams for High-Power Free-Electron Masers Based on Two-Dimensional Periodic Lattices
Ivan Konoplev,P. MacInnes,Adrian W. Cross,L. Fisher,Alan D. R. Phelps,Wenlong He,Kevin Ronald,Colin G. Whyte,Craig Robertson +8 more
TL;DR: In this article, the authors present the studies of high-current magnetically confined annular electron beams and discuss their production and transportation through a coaxial beam channel which formed the interaction region of a free-electron maser.
Proceedings ArticleDOI
RF Pulse Compression Using Helically Corrugated Waveguides
P. MacInnes,Kevin Ronald,Graeme Burt,Adrian W. Cross,A. R. Young,Alan D. R. Phelps,Ivan Konoplev,Wenlong He,Sergey V. Samsonov,V. L. Bratman,G. G. Denisov +10 more
TL;DR: In this paper, the use of a helically corrugated waveguide as a dispersive medium for microwave pulse compression is described, and the results show that the compressor does not suffer from reflections associated with cut-off scenarios at frequencies close to its operating regime and may be used in conjunction with high power wideband tunable microwave sources and amplifiers.
Proceedings ArticleDOI
The dispersion characteristics of helically corrugated waveguide
Lei Zhang,Adrian W. Cross,Wenlong He,Craig Robertson,A. R. Young,Colin G. Whyte,Kevin Ronald,P. MacInnes,Craig R. Donaldson,Alan D. R. Phelps +9 more
TL;DR: In this paper, a summary of the methods used to study the dispersion characteristics of a five-fold helical waveguide is given, along with a comparison of the results.
