Wiggler improvement based on single axis magnetic measurement , synthesized 3-D field simulation of trajectories and sorting of lateral focusing magnets

Abstract

A method is presented for correcting magnetic field imperfections in an assembled wiggler of the Halbach configuration. The method is employed in a configuration in which lateral focusing is needed along the wiggler (at low beam energies and large length) and is provided by external magnet bars alongside the wiggler. Field deviations in both vertical and… (More)
