FERMI (acronym for Free Electron laser Radiation for Multidisciplinary Investigations) is the seeded free electron laser (FEL) facility in operation for external users next to the third-generation synchrotron radiation facility Elettra. Unique among the FEL sources currently operating in the ultraviolet and soft x-ray range worldwide, FERMI has been developed to provide fully coherent ultrashort (10-100 femtosecond) pulses with a peak brightness ten billion times higher than that made available by third-generation light sources. FERMI opens unique opportunities for exploring the structure and transient states of condensed matter, soft matter and low-density matter using a variety of diffraction, scattering and spectroscopy techniques.

FERMI Beamlines and Photon diagnostics

FERMI Beamlines and Photon diagnostics

After the undulators the photon beam travels through a diagnostics section and the transport to reach the beamline endstations.

Free electron laser source

A linear accelerator is used to generate a relativistic electron beam that can be injected into each of two separate FEL lines, configured as single- and double-harmonic-cascade setups. An external laser is used to seed each of these lines.

FERMI 2.0 Conceptual Design Report

FERMI 2.0 CDR cover

The FERMI FELs are evolving to improve the source performances and to accomplish new needs coming from the user community according to  the lessons learned in the first ten years of user operation. In the next future, an upgrade aimed at extending the emission spectral range of FEL-2 to the water window and to allow pulse durations below the characteristic lifetime of atomic core holes in this energy range, is planned. A Conceptual Design Report focused on the upgrade strategy is available at the link: FERMI 2.0 Conceptual Design Report.
