Modeling high average current and high bunch charge beams in MICHELLE-eBEAM

Abstract

The MICHELLE-eBEAM code has been employed successfully for modeling high average current and high bunch charge beams using a time-dependent model. Accurate particle tracking with self-consistent space charge and image forces is important in modeling detailed phase space evolution of high charge electron bunches. The MICHELLE-eBEAM code presents a promising solution where the model resolution only depends on the number of particles modeled and the detailed phase space evolution is enabled by accurate Coulomb calculations facilitated by a GPU-based tree algorithm. In this paper we report on our latest progress and show validation and benchmarking results.
