Abstract
The beam transport system for the CEBAF Industrial FEL includes a two- pass transport of the beam with acceleration from injector to wiggler, followed by energy recovery transport from wiggler to dump. From that context, we discuss the general problem of multi-pass energy-recovery beam transport for FELs. Tuneable, nearly-isochronous, large-momentum -acceptance transport systems are required. The entire transport must preserve beam quality, particularly in the acceleration transport to t he wiggler, and have low losses throughout the entire system. Various possible designs are presented and results of dynamic analysis are dis cussed.
