Use of Projectional Phase Space Data to Infer a 4D Particle Distribution
We consider beams which are described by a 4D transverse distribution f(x, y, x', y'), where x' {triple_bond} p{sub x}/p{sub z} and z is the axial coordinate. A two-slit scanner is commonly employed to measure, over a sequence of shots, a 2D projection of such a beam's phase space, e.g., f(x, x'). Another scanner might yield f(y, y') or, using crossed slits, f(x, y). A small set of such 2D scans does not uniquely specify f(x, y, x', y'). We have developed ''tomographic'' techniques to synthesize a ''reasonable'' set of particles in a 4D phase space having 2D densities consistent with the experimental data. These techniques are described in a separate document [A. Friedman, et. al., submitted to Phys. Rev. ST-AB, 2002]. Here we briefly summarize one method and describe progress in validating it, using simulations of the High Current Experiment at Lawrence Berkeley National Laboratory.
