CARM driver for high frequency RF accelerators

The CARM (cyclotron autoresonance maser) is a promising source of microwave power for the next generation of linear collider. Designs for a high-power 17.136-GHz CARM amplifier, utilizing a 700-kV pulse modulator and a 1.2-MeV linear induction accelerator, are presented. These designs are attractive for a proof-of-principle CARM amplifier experiment. Interaction efficiencies are in the 30-50% range; higher efficiencies should be possible with nonlinear tapers.<<ETX>>
