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.

The Gun Test Facility (GTF) at SLAC serves as a test bed for electron gun and high brightness photoinjector developement for future short wavelength light sources as well as new or improved diagnostics techniques. We report on measurements of longitudinal and projected as well as time-resolved transverse electron beam properies over a wide range of charge from 15 to 600 pC. The transverse and longitudinal phase space distributions are compared with simulation results.
