An intense, sub-picosecond, relativistic electron beam traversing a dielectric lined waveguide generates very large amplitude electric fields at terahertz (THz) frequencies through the wakefield mechanism. In recent work employing this technique to accelerate charged particles, generation of high-power, narrowband THz radiation was demonstrated [ ]. The radiated waves contain fields with measured amplitude exceeding 2 GV/m, orders of magnitude greater than those available by other THz generation techniques at narrow bandwidth. For fields approaching the GV/m level, a strong damping has been observed in SiO2. This wave attenuation with onset near 850 MV/m, is consistent with changes to the conductivity of the dielectric lining and is characterized by a distinctive latching mechanism that is reversible on longer time scales. Here, we describe the detailed measurements that serve to clarify the underlying physical mechanisms leading to strong field-induced damping of THz radiation (hω = 1.59 meV, f = 0.38 THz) in SiO2, a bulk, wide band-gap (8.9 eV) dielectric.
