Popis:	Electron pulses generated at the Stanford SUNSHINE facility with (2–4.6)×108 electrons per microbunch have been measured as short as 50 fs (rms). The bunch length is determined by optical autocorrelation via a far‐infrared Michelson interferometer using coherent transition radiation emitted at wavelengths longer than and equal to the bunch length. This frequency‐resolved autocorrelation method demonstrates a better sub‐picosecond resolving power than any existing time‐resolved method. The experimental setup and the results will be described.
