	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.

TU2A1	Coherent Free-electron Laser Pulses: The User Perspective
	G. De Ninno Elettra-Sincrotrone Trieste S.C.p.A., Basovizza, Italy
	Are fully-coherent pulses the Holy Grail for experiments, which aim at taking full advantage of the properties of a free-electron laser (FEL)? What are the strategies to generate and diagnose them at seeded FEL facilities? What are the requirements for experiments based on pulse shaping and coherent control? How goes it for quantum coherence and the possibility to generate FEL pulses with sub-Poissonian statistics? We will talk about all this and more.

	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.
