We used time-resolved pump-probe core level photoemission spectroscopy to study the transient regime of the charge distribution at ${\mathrm{SiO}}_{2}/\mathrm{S}\mathrm{i}$ interfaces after photoexcitation with an UV free electron laser. We found tha

A collimated tunable gamma-ray beam has been generated by inverse Compton scattering of an additional positron bunch with the Super-ACO storage ring free-electron laser (FEL) positioned inside the optical resonator in the UV range (345-355 nm). This

The potential of UV-storage ring free electron lasers (SRFELs) for the performance of original application experiments is shown with a special emphasis concerning their combination with the naturally synchronized synchrotron radiation (SR). The first

Storage ring free electron lasers have a complex dynamics as compared to the LINAC driven FEL sources since both the laser and the recirculating electron beam behaviours are involved. Electron beam perturbations can strongly affect the FEL operation

Simulations with a simple model of wake field may lead to important coherent dipolar and quadrupolar synchrotron oscillations. We show that the free electron laser can suppress these oscillations leading to a stabilization of the electron bunch. Thes

The operation of storage-ring free-electron lasers (SRFEL) at high current still represents a challenge because of the growth of longitudinal beam instabilities. One of these, the quadrupolar coherent synchrotron oscillation, is very harmful for free

Storage Ring Free Electron Laser (SRFEL) sources can be implemented on synchrotron radiation facilities. Although in the beginning an additional experiment on the accelerator requires specific operating conditions as on Super-ACO at Orsay (France), t

The recent installation of a 500 MHz RF cavity on the storage ring Super-ACO allows the positron bunch to be reduced by a factor of 3. The first tests on the positron beam started at the end of March this year: besides the bunch length reduction obse

High-energy γ-photons have been produced by an intra-cavity Compton Back Scattering (CBS) process between the Super-ACO Storage Ring Free Electron Laser, at 350 nm, and an ultra-relativistic (800 MeV) positron bunch. No spatial selection of the beam
