A new Elettra
 

The Elettra 2.0 upgrade is designed to significantly enhance the brilliance and coherence of the X-ray source, surpassing the capabilities of the current Elettra facility. This improvement will be achieved without compromising the stability and reliability for which Elettra is known and without increasing operational costs. As a fourth-generation storage-ring-based X-ray source, Elettra 2.0 leverages cutting-edge advancements in accelerator technologies, including state-of-the-art magnet design, multibend lattices, and vacuum systems featuring non-evaporable getters. These innovations will allow a significant reduction in the emittance of the stored electron beam, thereby minimizing beam dimensions and giving rise to a diffraction-limited source in both the horizontal and vertical planes—a milestone already achieved vertically by third-generation sources like Elettra.

The existing 12-fold two-bend achromat lattice of Elettra will be replaced by a modern 12-fold symmetric six-bend achromat lattice (S6BA-E). This advanced design will reduce the horizontal emittance by approximately 50 times, increasing X-ray brilliance and coherence by more than two orders of magnitude. The machine will operate primarily at an energy of 2.4 GeV with an emittance of 212 pm rad, though operation at 2.0 GeV with an emittance of 147 pm rad is envisioned during an initial transition period.

The Elettra 2.0 upgrade ensures that Elettra - Sincrotrone Trieste will remain at the forefront of synchrotron radiation development and applications worldwide.
