Abstract

Currently there is significant interest in the use of storage rings to search for an electric dipole moment (EDM) in hadrons. This requires utilizing the storage ring as a precision measuring device. Part of understanding the detailed behavior of storage rings comes from careful analysis of fringe fields, but the various tracking codes available differ in their ability to model such behavior. It is the purpose of this paper to investigate these differences.
