Storage Accelerator Bending Magnet without Median Plane Symmetry

An H-magnet with no median plane symmetry, in which all the current carrying coils lie below the median plane, has been studied using the GRACY magnet program. This magnet was suggested by A. vanSteenbergen and has several possible advantages for use in a super-conducting storage accelerator. The field multipoles violating median plane symmetry were found to be small, and correctable with small correction coils. In addition, it was found possible to reduce these undesired multipoles considerably by shaping the iron pole face.
