Development of a Self-consistent Particle-in-cell (pic) Code Using a Time-adaptive Mesh Technique∗
نویسندگان
چکیده
For a large class of problems the self-consistent simulation of charged particle beams in linear accelerators is necessary. Typically, Particle-In-Cell (PIC) simulations use a fixed computational grid which has to resolve the bunch adequately. This leads to enormous memory consumption. Therefore, and especially in the 3D case, only rather short sections can be simulated. A remedy to this limitation is the usage of a dynamic grid which is automatically refined in the vicinity of particles. For this purpose, a new code, SMOVE, based on a time-adaptive grid is being developed. First promising results are presented in this paper.
