Summary
A superconducting X-ray free-electron laser under construction since 2018, the third in the world after European XFEL and LCLS-II, with three undulator lines and a photon range of 0.4–25 keV.
Now as of 4 Nov 2026
According to an IPAC'26 contribution, commissioning starts in July 2026 after the cryomodules are cooled down: first the accelerator and the FEL-II line at about 4 GeV, aiming at first lasing around 200 eV (JACoW IPAC'26). The project is due to be completed by the end of 2027 (Yicai). First lasing has not yet been confirmed in the sources found.
