FIG. 1.

Wakefield produced by FACET's 1 nC, σz = 30 μm beam in a 150 μm ID/250 μm OD quartz tube.

(Left) Simulation of the wakefield (red curve), produced by a triangular shaped current pulse (blue curve) in a THz wakefield structure (vertical scale is arbitrary). (Right) Energy-longitudinal coordinate dependence of an electron bunch (red – initial phase space) passing through a wakefield structure and experiencing energy modulation (blue) followed by compression in a chicane (green).

FIG. 3.

Example of bunching correction by changing the strength of the chicane. Red curve: original beam in longitudinal phase space. Blue: beam overmodulated in energy after passing through the wakefield structure. Yellow curve: beam after a weak chicane. Green curve: beam after an optimal chicane. Note the beam bunching growth and shift towards higher frequency.
