Title: Advanced RF Acceleration

Abstract: For decades conventional RF accelerators have been built and operated with
ever increasing capability thru a few tens of gigahertz in frequency. More recent
research takes advantage of the continuing development of high peak power short pulse
lasers to drive accelerator structures at optical frequencies. This jump from RF to optical
frequencies skips four orders of magnitude in wavelength. With recent experiments that
demonstrate high gradients in metallic structures at millimeter wavelengths one is
compelled to consider the viability of new approaches for acceleration in the millimeterwave
to terahertz regime. This talk will review recent developments in RF acceleration
gradient limits, novel RF sources and then explore some of the possibilities for mmwave/
THz accelerator systems.
