The production of high power microwave radiation at high harmonics of the electron cyclotron
frequency by the interaction of a rotating electron beam with a magnetron-type conducting
boundary has been studied theoretically and experimentally using a 2-MeV, 1-2-kA, 10-ns
electron beam pulse. Approximately 10% of the electron beam power has been converted to
microwave radiation at the 12th harmonic, and about 2% at the 20th harmonic. Radiation
characteristics are in good agreement with a theoretical analysis of the resonant interaction of a
beam mode with the modes of the conducting boundary system. Radiation from rotating beams in
"glide-symmetric" boundary systems is also reported.
