Description

Tracking through RF cavities is complicated due to the presence of electric and magnetic fields, both of which are time-varying and therefore not amenable to algorithms developed for static fields. Many simulation programs will implement simplified models such as zero length cavities with no transverse focusing or will offer tracking through field maps that are only approximately Maxwellian, and therefore not symplectic, and which potentially can be slow.

Presented here is an RF cavity model which has a number of advantages. It is rigorously symplectic and maps of arbitrary order can be computed, it reproduces the transverse focusing of Rosenzweig and Serafini, solenoid and multipoles can be included in the simulation. Additionally, particles can be efficiently tracked to reduce computation time. This algorithm has been incorporated as part of the Bmad ecosystem of libraries and programs and can be used with any Bmad based program.
