Abstract
We report the results of a study comparing an analytical theory of wig gler errors in free-electron lasers (FEL's) to a numerical simulation. The different mechanisms of reduction in FEL gain due to wiggler erro rs are reviewed, and in each case analytical results are compared with computer simulation and shown to be in good agreement. We present a s tudy of the proposed UV FEL user facility at BNL and determine the imp lications of the wiggler errors on the FEL design.
