Abstract
The visible free electron laser (FEL) experiment at the accelerator te st facility (ATF) at Brookhaven National Laboratory is designed to uti lize the high brightness beam from a laser-photocathode rf gun injecte d into a 50 MeV S-band linac in conjunction with a 8.8 mm period undul ator. The undulator is designed to provide a 0.5 T field on axis which is reached at a current 15% below the quench current. It consists of 3 contiguous sections. We discuss the held errors by evaluating the tr ajectory wander and the optical phase error. Whereas undulator section s with low errors can be built as machined without any shimming or tri mming, special care has to be taken during the assembly of a full leng th device.
