Description
Particle in-cell (PIC) codes as a means of simulating accelerator beams become resource intensive when simulation of the fine structure of a beam is necessary. We propose an alternative scheme wherein multiple macro-particles are replaced with super macro-particles; computational objects which encode not only the position and velocity data of a group of particles, but also some of the moments of the underlying particle distribution. By propagating the moments of the underlying distribution, the structure of the super macro-particle is allowed to evolve through time. We conjecture that this scheme will be able to simulate phenomena including bunching and inter-bunch interactions at a reduced resource cost.
