Abstract | For a range of acclerator applications, accurate simulation of electron-cloud effects requires self-consistent simulation of electrons and the main positively-charged accelerated species. For systems with multipole focusing magnets, the simulation must span timescales from electron cyclotron periods to the beam duration. We have devised a scheme to bridge over the shortest (electron cyclotron) timescale based on interpolation between full dynamics and drift kinetics.* We describe the method and results for heavy-ion beam simulations. We also discuss options for bridging to ion-transit timescales. |
