  Short and long term upgrade plans of the FERMI free-electron laser facility at Elettra Sincrotrone Trieste, Italy, will be reported. They include the ongoing linear accelerator energy upgrade and the conversion of the first undulator line to echo-enabled harmonic generation. The upgrade of the second undulator line to a two stage echo-based fresh-bunch scheme is also under study.

  A number of recent experimental and theoretical studies have investigated novel techniques for suppressing the microbunching instability in high-brightness linac-based light sources. This instability has long been studied as one of the causes of reduced longitudinal coherence in these machines, which are commonly suppressed using a laser heater. This contribution presents recent developments concerning the use of an optics-based scheme to mitigate the microbunching instability in the FERMI free-electron laser, paving the way towards reversible beam heating techniques that could improve the performance of future machines.
