Description
Phase space tomography of intense beams is challenged by a self-consistency problem: space charge depends on the unknown distribution. We introduce a transport-free tomography framework that reconstructs high-dimensional phase space using single-optics, single-location measurement schemes, thereby eliminating the need to model space charge. We discuss measurement schemes that extract sufficient cross-plane data, and show how high-dimensional geometry tools can guide the choice of device and measurement parameters to minimize sensitivity to errors. Maximum entropy tomography is established as an effective method for reconstructing high-dimensional distributions from measured projections. Finally, we demonstrate how f-divergences can be calibrated to quantify distribution differences, enabling systematic verification of measurement schemes and interpretation of results.
