Abstract
An electromagnetic wiggler having a cylindrical member, and a central member disposed axially within the cylindrical member, both of which are formed from alternating cylindrical sections of ferromagnetic and non-ferromagnetic material, each sequential pair of these sections being the length of the wiggler's period .lambda..sub.w. The sequence of sections between the inner and outer members is shifted .lambda..sub.w /2, so that ferromagnetic sections of the outer member are disposed radially opposite non-ferromagnetic sections of the inner member, and vice versa. The resultant radial magnetic flux density in the cylindrical gap between the members is larger and sharper than the flux density for the same wiggler without the central member, permitting higher radiated power output, at higher radiation frequencies, for the same energy of input electron beam.
