The newly developed intense short wavelength light sources (from Extreme Ultra-Violet (EUV) to X-rays) have open the path to the exploration of matter for revealing structures and electronic processes and for following their evolution in time. After

Free-electron laser (FEL) operations in a storage ring operating in a low emittance and reduced momentum compaction factor setting are here presented with reference to the experimental case of Super-ACO. The new working point of the storage ring has

To take complete benefit of the Free Electron Laser (FEL) features, we have developed a feedback control scheme designed to suppress the dynamical instabilities affecting the FEL output intensity. The principle is to stabilize an unstable stationary

In a Storage Ring Free Electron Laser (SRFEL) there is a strong interdependence between the laser beam and the electron beam from which the laser is generated. The Super ACO storage ring has a second Radio Frequency (RF) cavity at the 5th harmonic of

The operation of the Super-ACO storage ring FEL using a harmonic RF cavity exhibits vertical instabilities, which are generally compensated with an increase of the chromaticity of the operating point. It has been previously reported that the FEL itse

The response of the Free Electron Laser (FEL) to an external perturbation can be studied by applying a laser gain modulation. When its frequency is close to the laser resonance one, a non-linear gain variation of the Super-ACO storage ring FEL can le

In this paper we illustrate the main features of a new scheme which aims at obtaining coherent radiation at very short wavelengths (down to 1.5 nm) by using the Harmonics of an intense laser, generated in a gas, as a seed to inject in a long undulato
