Phys. Rev. Lett. 88, 064801 (2002) [3 pages]Free-Electron RF-Pulse CompressorReceived 14 August 2001; published 25 January 2002 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. © 2002 The American Physical Society URL:
