    "abstract": "In this paper we present results of using parallel supercomputers to simulate\nbeam dynamics in next-generation high intensity ion linacs. Our approach uses a\nthree-dimensional space charge calculation with six types of boundary\nconditions. The simulations use a hybrid approach involving transfer maps to\ntreat externally applied fields (including rf cavities) and parallel\nparticle-in-cell techniques to treat the space-charge fields. The large-scale\nsimulation results presented here represent a three order of magnitude\nimprovement in simulation capability, in terms of problem size and speed of\nexecution, compared with typical two-dimensional serial simulations. Specific\nexamples will be presented, including simulation of the spallation neutron\nsource (SNS) linac and the Low Energy Demonstrator Accelerator (LEDA) beam halo\nexperiment.",
