Modeling and Particle Tracking through Longitudinal Gradient Bending Magnets

Abstract

This report documents the development of a versatile model for longitudinal gradient bending magnets (LGB's) and its implementation in particle tracking simulations. The model presented below may be used to represent an arbitrary magnetic field profile, and was successfully implemented to represent two different LGB's. After building a symplectic integrator for our model, we were able to perform particle tracking studies. By producing phase space plots which depicted stable trajectories, we were able to demonstrate that we had in fact correctly implemented our symplectic integration scheme. In addition, we produced stack representations for the bending component of the magnetic field for each LGB and made preliminary comparisons between lattices implementing this model and our own.
