Applications of UV-storage ring free electron lasers: the case of super-ACO

The potential of UV-storage ring free electron lasers (SRFELs) for the perf ormance of original application experiments is shown with a special emphasi s concerning their combination with the naturally synchronized synchrotron radiation (SR). The first two-color FEL + SR experiment, performed in surfa ce science at Super-AGO is reported. The experimental parameters found to b e the most important as gathered from the acquired experience, are underlin ed and discussed. Finally, future prospects for the scientific program of t he Super-AGO FEL are presented with two-color experiments combining the FEL with SR undulator-based XUV and VUV beamlines as well as with a SR white l ight bending magnet beamline emiting in the IR-UV (20 mu m-0.25 mu m).
