ELETTRA is a multidisciplinary Synchrotron Light Laboratory in AREA Science Park, open to researchers in diverse basic and applied fields. The laboratory is equipped with ultra-bright light sources in the spectral range from UV to X-rays and offers a stimulating and competitive environment to researchers from all over the world.

A collaboration contract with the MAX-lab, Lund (Sweden), has been signed to progress significantly with the activities on the FERMI@Elettra electron source till the FERMI building extension is completed.

The project aim is to perform the acceptance test of the FERMI Gun delivered by UCLA and to start its commissioning using the existing S-band 25 MW klystron and the existing photoinjector UV laser (262 nm, 10 ps duration and 500 J pulse energy available).

The crucial elements of the FERMI photoinjector (RF cavity, magnets, laser beam diagnostics and transport and electron beam diagnostics) have been installed in the injector tunnel of MAX-lab, as shown in Figure 1, during Easter shutdown.
