The Elettra 2.0 Beamlines

The Elettra 2.0 project was approved by the Italian Government in 2017, with plans for the new machine to commence serving external users in 2027. The design phase lead to a final version of Elettra 2.0 a fully transversely coherent source up to 0.5 keV-photon energy, more than doubling the total average current and increasing brightness by more than two orders of magnitude as compared to the current source, and maintaining a diversified beamline portfolio to allow experiments across a broad spectrum of photon energies, from a few tens of eV to several tens of keV, while substantially increasing the number of beamlines operating in the hard-X-ray range. In perspective, the possibility of producing picosecond-long light pulses at a MHz repetition rate across multiple beamlines simultaneously, without interference to standard multi-bunch operation is also being considered. Another important aspect of Elettra 2.0 is the high degree of transverse coherence in both the horizontal and vertical directions, projected to improve by a factor of 60 at 1 keV as compared to the current source.
