Fast tracking of nonlinear dynamics in the ESS linac simulator via particle-count invariance

Folsom, B. LU and Laface, E. LU (2016) 7th International Particle Accelerator Conference, IPAC 2016 p.3080-3082
Abstract

Real-time beam modeling has been used in accelerator diagnostics for several decades. Along the way, the theory for matrix calculations of linear forces has matured, allowing for fast calculations of a beam's momentum and position distributions. This formalism becomes complicated and ultimately breaks down with high-order beam elements like sextupoles. Such elements can be accurately modeled with a Lie-algebra approach, but these techniques are generally implemented in slower, offline multiparticle tracking software. Here, we demonstrate an adaptation of the conventional Lie techniques for rapid first-order tracking of position, which is accomplished by treating a bunch's particle count as an invariant.
