ABSTRACT: We have developed a new, comprehensive set of simu-lation tools aimed at modeling the interaction of intense ion beams and electron clouds (e-clouds). The set contains the 3-D accelerator PIC code WARP and the 2-D "slice" e-cloud code POSINST [M. Furman, this workshop, pa-per TUAX05], as well as a merger of the two, augmented by new modules for impact ionization and neutral gas gen-eration. The new capability runs on workstations or par-allel supercomputers and contains advanced features such as mesh refinement, disparate adaptive time stepping, and a new "drift-Lorentz" particle mover for tracking charged particles in magnetic fields using large time steps. It is be-ing applied to the modeling of ion beams (1 MeV, 180 mA, K+) for heavy ion inertial fusion and warm dense matter studies, as they interact with electron clouds in the High-Current Experiment (HCX) [experimental results discussed by A. Molvik, this workshop, paper THAW02]. We de-scribe the capabilities and present recent simulation results with detailed comparisons against the HCX experiment, as well as their application (in a different regime) to the mod-eling of e-clouds in the Large Hadron Collider (LHC).
