Abstract
To enhance the FEL harmonic gain, we have developed a wiggler having a harmonic wiggler field. The modified wiggler consists of a convention al planar wiggler and high-permeability shims. Because of this simplen ess, we can develop a wiggler having various types of modified fields, easily and economically. We show the design basis of the modified wig gler and examples of them which contain one harmonic field. Then, we i ntroduce the FEL experiment of the 5th harmonic generation with a modi fied wiggler. (C) 1998 Published by Elsevier Science B.V. All rights r eserved.
