Quasi-sheet multipole permanent magnets

A Rare-Earth Permanent Magnet design system with which a desired pure multipole field can be achieved by accurately deploying REPM blocks around a working region so as to generate magnetic sheet currents which follow the profile of a magnetically soft yoke is presented here. In addition to the general Quasi-Sheet Multipole model, examples of two small operating QSM quadrupoles together with a large QSM dipole are also described.
