Results of a feasibility study are summarized for multi-megawatt mm-wavelength gyroharmonic converters for plasma heating applications. Output power in these devices is extracted at a high harmonic of the modulation frequency of a spatiotemporally gyrating electron beam prepared using cyclotron autoresonance acceleration. An example is described in which an output of 2.2 MW at 148.5 GHz is predicted at the 13th harmonic of an 8 MW 11.424 GHz CARA, after including waveguide ohmic wall losses. Achievement of this performance requires a high quality 200 kV, 16 A luminar pencil beam injected into CARA, and effective suppression of competing output modes; means to realize these requirements are discussed.
