Proceedings ArticleDOI
Backward Scattering of High-Power Microwaves by Subnanosecond Relativistic Electron Beam
TL;DR: In this paper, the effect of superradiation pulses was first observed during the induced backward scattering of a high-power pump microwave by a short high-density relativistic electron beam.
Proceedings ArticleDOI
Microwave pulse compression using helically corrugated waveguides and its potential for generating ultra-high power RF radiation
Graeme Burt,Sergey V. Samsonov,Kevin Ronald,V. L. Bratman,A. R. Young,G. G. Denisov,Alan D. R. Phelps,Adrian W. Cross,Ivan Konoplev,Wenlong He +9 more
TL;DR: In this article, the use of a helically corrugated waveguide as a dispersive medium for microwave pulse compression is presented, which can be used at the output of a high-power microwave device.
Proceedings ArticleDOI
Compression of pulses from a relativistic bwo using helically corrugated waveguides
