Abstract :
Pulsed rf heating is a fundamental limit on high-gradient acceleration in copper structures. Reduction of pulsed heating is favored by a short exposure time for the copper; yet in conventional accelerators, efficiency requires an exposure time of order of the cavity fill time. At the W-Band, the cavity beat-wave transformer concept permits efficient energy transfer to resonant accelerating modes on a sub-nanosecond time-scale. We reexamine this acceleration scheme as it appears at the W-band, with attention to drive beam dynamics
