  FERMI is the seeded Free Electron Laser (FEL) user facility at the Elettra laboratory in Trieste, operating in the VUV to EUV and soft X-rays spectral range; the radiation produced by the seeded FEL is characterised by a number of desirable properties, such as wavelength stability, low temporal jitter and longitudinal coherence. In this paper, after an overview of the FELs performances, we will present the development plans under consideration for the next 3 to 5 years. These include an upgrade of the LINAC and of the existing FEL lines, the possibility to perform multi-pulse experiments in different configurations and an Echo Enabled Harmonic Generation experiment on FEL-2, the FEL line extending to 4 nm (310 eV).

Photon Beam Transport and Diagnostics Systems at an EUV FEL Facility: General Considerations, and Specific Challenges, Solutions and Developments at the FERMI Seeded FEL

  After the start of FLASH user operations in 2005, the possibility of performing user experiments at an EUV free electron laser source became reality. This kind of opportunity was extended in 2012 when the Italian FERMI seeded-FEL user facility started its user program. As a consequence, for such light sources new photon transport and diagnostic solutions were designed, developed, and implemented. A brief general overview about these issues will be introduced, together with a more detailed presentation of challenges faced and solutions found at the FERMI FEL. In particular, different instruments were developed in order to meet machine and endstation users' requirements concerning online non-invasive spectral content determination, pulse length and intensity characterization/control, active modification of the focusing properties, etc. Some examples and results will be presented, possibly comparing them to what was done elsewhere. Possible future implementations in photon-beam manipulation and characterisation will also be discussed.
