Abstract

We have developed dielectric-lined rectangular waveguide structures for terahertz (THz)-driven ultrafast deﬂection of 100 keV electron beams. The structures were designed to achieve THz phase velocity matching with co-propagating electron bunches. The phase-matching capability was experimentally conﬁrmed through time-frequency analysis of the broadband coherent THz transmission measured by electro-optic sampling. The analysis determined both the frequency dependent propagation constants in the electron interaction region, and the propagation characteristics of the integrated THz tapered coupler.
