The determination of an electron beamʹs longitudinal phase space distribution through the use of phase-energy measurements

We have been able to measure the longitudinal phase space distribution of the Stanford Superconducting Acceleratorʹs (SCA) electron beam by applying tomographic techniques to energy spectra taken as a function of the relative phase between the beam and the accelerating field. The temporal profile of the beam obtained by projecting the distribution onto the time axis is compared with that obtained from interferometric transition radiation measurements.
