An efficient discretization of phase space is exploited, using conservation of charge and current in hypertriangle patches, to reconstruct the current density by fitting Gaussians through the distorted hypertriangles. Advantages and limitations are discussed.application/pdfenIn CopyrightCurrent densityElectron beamsCharged currentsComputer simulationComputer simulation of electron beams. II.
