Planar Permanent Magnet Multipoles For Particle Accelerator And Storage Ring Applications

In prior work a planar permanent magnet. (PM) configuration for generating an approxinlat~e quadrupole field distribut,ion in the vicinity of its symmetry axis was disclosed. In the present paper extensions of the inet,hod are considered for generat,ing sextupole and higher order multipole fields. The field distributions and strengt,hs are contrasted with idealized (azimuthally periodic) mulhipole field generators and select.ed applications in the area-of single-pass and recirculat,ing particle machines are considered.
