ABSTRACT:
Periodic permanent magnet (PPM) stacks for use in wigglers and traveling e tubes having magnetic cladding. A variable magnetic potential cladding along the adjacent surfaces of working magnets is used, thereby increasing the efficient use of magnetic material and increasing the magnetic field while minimizing weight. The magnetic cladding has a direction of polarity perpendicular to the direction of polarity of the working magnets. Extraneous magnetic fields are also reduced. A magnetic shunt, or soft iron, is used to facilitate the conduction of magnetic flux and create an equal magnetic potential exterior surface.
