SHINE Hard X-ray Free-Electron Laser Facility Achieves First Light
Topics and contents
On October 15, 2026, the Hard X-ray Free-Electron Laser Facility (SHINE) achieved first light, moving a step closer to completion and commissioning by the end of 2027. The electron beam produced by a 4 GeV continuous-wave superconducting linac drives a series of 18 undulator lines, each 4 meters long with a 55 mm magnetic period. Once completed, the electron energy will reach 8 GeV, and the first two undulator lines will produce free-electron laser radiation covering 0.2 to 15 keV, with optical pulses as short as femtoseconds and a maximum repetition rate of up to 1 MHz.
The facility's first light is presented separately from its design specifications after completion, helping to clarify the construction stages and research capabilities of a CW superconducting accelerator free-electron laser facility.
