Abstract
A wiggler design has been developed which is scalable to small periods with high field amplitude, high beam current acceptance, and excellen t transverse focusing and beam propagation properties. The coaxial hyb rid iron (CHI) wiggler design consists of a coaxial arrangement of alt ernating ferromagnetic and non-ferromagnetic rings with the central po rtion of the coax shifted by one half period. The entire arrangement i s immersed in a solenoidal field which results in a cylindrically symm etric periodic field. FEL configurations using this wiggler design hav e the potential for high power, high frequency coherent generation in relatively compact systems. Analytic and simulated characteristics of the CHI wiggler are discussed.
