Free-electron RF-pulse compressor.
A spatially modulated (corrugated) electron beam provides Bragg-type scattering of two waveguide modes. This allows the use of corrugated beams as quick active elements in rf-pulse compressors. In an illustrative example shown with a peak power compression ratio of 20-40, a 10-20 ns output pulse with a peak power of tens of MW is predicted for a millimeter-wavelength compressor.
