  FERMI is the seeded FEL user facility in Trieste, Italy, producing photons from the VUV to the soft X-rays with a high degree of coherence and spectral stability. Both FEL lines, FEL-1 and FEL-2, are now available for users, down to the shortest wavelength of 4 nm. We will report on the completion of the commissioning of the high energy FEL line, FEL-2, and on the operational experience for users, in particular those requiring specific FEL configurations, like two-colour experiments. We will also give a perspective on the improvements and upgrades which have been triggered by our experience and are aiming to maintain as well as to constantly improve the performance of the facility for our user community.

  The S-band linac of FERMI, the seeded Free Electron Laser (FEL) located at the Elettra laboratory in Trieste, operates on a 24/7 basis accumulating more than 6000 hours of operation per year. The performance and operability requirements of a users facility pose stringent specifications on reliability and availability on all the systems of the machine and in particular on the RF power plants. This paper provides a review and discusses the operational experience with the S-band power plants, klystrons and modulators, operating at S-band in FERMI. Based on the satisfactorily results and following return of experience, upgrades of the existing power plants are being implemented in the continuous effort of extending the operability and availability of the systems. A description of these activities and an overview of the other developments under consideration on the RF power plants are also provided.
