Abstract
A permanent magnet, ‘‘bifilar’’ helical wiggler for use in free-electron lasers and cyclotron masers has been designed, assembled, and measured. It is composed of a cylindrical array of staggered samarium-cobalt bar magnets, transversely magnetized and held in place in an axially grooved hollow metal cylinder. High-quality helically polarized fields of several kilogauss can be readily achieved.Keywords
