UNDULATORS FOR THE BESSY SOFT-X-RAY FEL

BESSY plans to build a linac based Soft-X-ray FEL facility. Three FEL lines will cover the energy range between 24eV and 1000 eV. The FELs are operated in a high gain harmonic generation scheme providing short pulses and stable operation. This paper describes the undulator systems for the FELs.
