  FERMI is the Italian externally seeded free electron laser in the UV and soft x-rays, driven by a high brightness electron beam S-band plus X-band linac. In recent times, the linac has been upgraded, leading the final beam energy from the design value of 1.2 GeV to 1.5 GeV. Together with proper management of the electron beam quality, fundamental wavelengths down to 4 nm become therefore accessible to users. Additional upgrades concerning laser systems, diagnostics and RF structures are on the path. We present the FERMI FEL linac status, and provide an overview of running and future capabilities of the facility.

  FERMI is a seeded Free Electron Laser (FEL) driven by a warm S-band Linac. In the injector region, two 3- meter long Forward Traveling Wave (FTW) accelerating structures, coming from the old Elettra injector, were installed. In order to improve the e-beam quality at higher bunch charge, it was decided to replace the existing ones with two dual-feed accelerating structures. Those structures have been designed and manufactured by RI Research Instruments GmbH and delivered to Elettra in July 2015. The following paper will report about the RF design and the manufacturing of the new structures. Details about the RF conditioning and the installation will also be illustrated.
