Generalized space-charge solver for three-dimensional converging or diverging beams
Ji Qiang
Nonlinear space-charge effects play a critical role in the dynamics of high-intensity, high-brightness beams. While conventional space-charge forces scale inversely with the square…

Poisson solvers for self-consistent multi-particle simulations
J. Qiang, S. Paret
Self-consistent multi-particle simulation plays an important role in studying beam-beam effects and space charge effects in high-intensity beams. The Poisson equation has to be sol…
