摘要
There have been extensive studies on the effects of intrinsic field errors on the operation and performance of free electron lasers (FELs) based predominately on simple models for the spatial form and statistical properties of the field errors. In some cases, the effects of compensation magnets or steering coils have been included as a method of reducing the deletrious effects of field errors. In the present study we consider the effects of (i) compensation magnets, (ii) general spatial forms which are more realistic models of experimental wigglers and (iii) statistical correlations of the field errors. This theoretical study has resulted in a quantitative means of measuring the relative merit of these experimental techniques for reducing wiggler field-error effects. These means of comparative analysis yield important criteria for experimental design and modeling. © 1990.
