Abstract :
We analyze particle diffusion and emittance growth induced by discrete-particle effects in two-dimensional self-consistent numerical simulation studies of beam dynamics. In particular, an analytical model is presented which describes the slow time-scale variation of edge emittance for a perfectly matched beam in a periodic solenoidal magnetic focusing field. A scaling law for edge emittance growth is obtained
