Understanding and optimizing the beam dynamics in high brightness electron accelerators not only requires the measurement of the 6-D beam ellipse, but also the details of the phase space distribution. By combining longitudinal and transverse phase space tomography in a dipole spectrometer the four-dimensional distribution can be resolved. We report on experiments at the Gun Test Facility (GTF) at SLAC where we measure the energy resolved horizontal beam distribution while simultaneously varying the longitudinal time-energy correlation and the horizontal phase advance to reconstruct the horizontal-longitudinal phase space distribution.
