AB  - We present an algorithm to tomographically reconstruct the 4D phase space of a beam distribution of a high brightness electron beam, based on the use of two fluorescent screens separated by a beamline containing a quadrupole triplet which can be used to impart arbitrary rotations to the beam phase space. The reconstruction method is based on generating a macroparticle distribution which matches the initial profile and then it is iteratively updated using the beam projections on the second screen until convergence is achieved. This process is repeated for many quadrupole current settings. The algorithm is benchmarked against GPT simulations, and then implemented at the UCLA Pegasus beamline to measure the phase space distribution for an upcoming high speed electron microscope experiment.
