Description
We use the PHOEBE test beamline at Cornell to experimentally demonstrate a simple method for reconstructing the transverse 4D phase space of an electron beam at the source from downstream aperture scans of the beam. This method does not rely on detailed knowledge of the beamline transport, besides assuming that linearity and symplecticity are satisfied. We apply this method to measure the source 4D phase space of electrons emitted from a spatially-structured alkali-antimonide cathode, and verify the fidelity of the reconstructed source spatial and momentum distributions.
