Abstract

Multiple-stage injections to an accumulator ring boost intensity until a final extraction delivers the full proton beam to a target transfer line. Kickers and an Extraction Lambertson Septum (ELS) magnet implement extraction. Studied here are various concerns of the design of an ELS magnet, including: lattice geometry, beam dynamics and optics considerations; and vacuum, electromagnetic and mechanical design aspects. Reference datum and transformations are established and shown schematically. Coil, yoke, and shield design optimization is discussed.
