Few-femtosecond electron beam with terahertz-frequency wakefield-driven compression
Few-femtosecond electron beam with terahertz-frequency wakefield-driven compression
We propose and demonstrate a novel method to produce few-femtosecond electron beam with relatively low timing jitter. In this method a relativistic electron beam is compressed from about 150 fs (rms) to about 7 fs (rms, upper limit) with the wakefield at THz frequency produced by a leading drive beam …
