Description
We introduce a novel scheme for the simulation of plasmas and accelerator beams: the moment-based particle-in-cell (PIC) code. This scheme is similar to a standard PIC code, with the key distinction being that the simulation objects have a dynamic shape. These simulation objects, called super-macroparticles (SMPs), are assigned a phase-space distribution at runtime, the dynamics of which are partially encoded in the moments of that distribution. We discuss methods for updating these moments at each timestep, as well as a procedure for depositing SMPs onto the computational grid. Finally, we present the remaining challenges that must be addressed before a complete implementation can be realized and outline possible applications for the moment-based PIC code.
