Powerful electromagnetic millimeter-wave oscillations produced by stimulated scattering of microwave radiation by relativistic electron beams
The results of analytical and experimental studies of stimulated electron scattering in relativistic cm- and mm-wave generators are reported. Carcinotrons and an orotron served as pump generators equipped with corrugated sides to produce a weak harmonic. The resulting beam collided with an electron beam propagating in the opposite direction and produced a scattered beam. The scattered wave frequencies are quantified, noting that the waves in the carcinotrons sometimes satisfied the Bragg condition and run in opposite directions, reflect off one another, oscillate, and can satisfy a synchronism criterion, which induces stimulated scattering. Trials performed with three different generating systems and beam voltages showed that a first order harmonic in a periodic waveguide of the carcinotrons was the same frequency as the scattering radiation. It is concluded that stimulated scattering is a viable technique for obtaining strong single-mode mm-wave signals when mode selection is used.
