Description
Based on a 1.5-GeV electron linear accelerator, FERMI@Elettra [1] has two seeded FEL lines that cover the whole spectral range from 100 nm down to 4 nm with fully coherent pulses. The use of the high gain harmonic generation scheme initiated by a tunable laser in the UV allows FERMI to produce light characterized not only by transverse coherence but also by a very high temporal coherence. The use of APPLE II undulators allows control of the FEL polarization that can be varied from linear to circular. Here we will report about the recent FEL commissioning results and the future plans for FERMI@Elettra.
