November 2015
This report details the performance of the circular pole dipole magnet to be used as an electron-positron pair spectrometerfor the Bethe-Heitler experiment at HIGS.The report describes the codes used to determine the expectedperformance of the spectrometer.Note that many changes have occurred in the design and thefunctionality of the code over the life of this project.Therefore this report is written in somewhat of a narrativestyle detailing our design choices as they occurred.This report should therefore be considered a living document.
