At the previous Linac Conference, we introduced a semianalytic Fokker-Planck formalism for calculating the evolution of intense, nonrelativistic, mismatched beams propagating through focusing channels. We have since elaborated on its physical basis and greatly expanded its applicability. In this paper, we implement the model to study the dynamics of a circularly symmetric beam propagating through a linear focusing channel. An example is discussed for an ion beam and accelerator parameters which are representative of high-current spallation neutron sources in which space-charge forces are important. The example illustrates the dynamics of emittance growth and halo formation in the beam.
