Abstract
The effect of a leading particle on a trailing particle due to resistive and geometric wakefields in collimators can be described by expanding in a series of angular mode potentials Wm(s). Several formulae for these are given in the literature. We compare these formulae with numerical predictions from codes that solve the EM field equations. We also show how the EM code results can be used to numerically obtain angular mode potentials suitable for use in tracking codes.
