Design of permanent multipole magnets with oriented rare earth cobalt material
Abstract
By taking advantage of both the magnetic strength and the astounding simplicity of the magnetic properties of oriented rare earth cobalt material, new designs have been developed for a number of devices. In this article on multipole magnets, special emphasis is put on quadrupoles because of their frequent use and because the aperture fields achievable (1.2-1.4 T) are rather large. This paper also lays the foundation for future papers on: (a) linear arrays for use as "plasma buckets" or undulators for the production of synchrotron radiation; (b) structures for the production of solenoidal fields; and (c) three-dimensional structures such as helical undulators or multipoles.
