Summary
Replaces the Elettra synchrotron, which ran for 32 years, with a fourth-generation ring: a twelvefold symmetric six-bend achromat (S6BA-E), running mainly at 2.4 GeV and 212 pm·rad, and at 2.0 GeV and 147 pm·rad during a transition phase (Elettra 2.0). The free-electron laser FERMI is on the same site.
Now as of 9 Nov 2026
The Elettra ring was switched off for good on 2 July 2025 (the "dark period"); dismantling was finished in November 2025, and the new ring is being installed (Indico PSI, May 2026, JACoW IPAC'26, MOP7144). According to the project schedule (updated 6 May 2026), the new source starts up in January 2027, open access to the first 15 beamlines follows in July 2027, then up to 32 beamlines, with the project finished in 2029 (timeline). The date has slipped: in 2025, commissioning with beam was planned from 15 September 2026; now it is January 2027 (IPAC'26, THP2039). Among the main risks is a delay in the radiation licence for operating with beam (ESLS 2025).
