摘要
It is shown that the lowest TE(s,l) mode in a cylindrical waveguide at frequency s omega, with group velocity nearly identical to group velocity for the TE(11) mode at frequency omega, is that with s = 7, l = 2. This allows coherent radiation to be generated at the seventh harmonic during electron cyclotron autoresonance acceleration. Conditions are found where such co-generation of 7th harmonic power at 20 GHz is possible with overall efficiency greater than 80%. This mechanism could make possible high efficiency cm-wavelength high power rf sources suitable for driving a future multi-TeV electron-position collider.
