  FERMI@Elettra is a seeded FEL user-facility covering the wavelength range from 100 nm (12 eV) to 4 nm (310 eV) located next to the third-generation synchrotron light source Elettra in Trieste, Italy. The facility is based on a normal conducting linac and covers the wavelength range with two FEL lines, FEL-1 and FEL-2. A photon distribution and diagnostic system transports the photons from the end of the two FEL lines to three experimental stations. Beneficial occupancy of the new undulator hall and experimental hall was given end of Summer 2010 when also all auxiliary systems were made available. The installation of the machine is now almost completed; commissioning of the linac has started in parallel to the installation activities and now commissioning of FEL-1 is in a well advanced status. The first seeded lasing from FEL-1 was actually observed in December 2010 and first experiments are starting in 2011. In this paper an overview of the facility will be given as well as the general status of installation and commissioning and a perspective into future developments and user programs.

  The FERMI@Elettra Free Electron Laser (FEL) produced the first coherent photons in December 2010 at the end of the first commissioning phase. Starting from February 2011 the commissioning has continued, leading to an improvement of the FEL performance. In agreement with to the design, FEL-1, the first of the two FERMI free electron lasers, has been producing coherent FEL pulses in the 60 to 20 nm wavelength range. Benefits of the seeded scheme adopted for FERMI have been immediately evident also in the case of a non-optimized electron beam.
