Description
Rory Ma and six co-authors demonstrate time-resolved iron K-edge XANES spectroscopy with a self-seeded X-ray free-electron laser, in work from 2025. The work was done at the PAL-XFEL facility in Pohang, using its FXL endstation. Self-seeded operation gives a steadier, narrower beam than the standard mode, which should sharpen fast chemical measurements.
An iron compound in water was excited with a femtosecond laser and probed by matched X-ray pulses. The self-seeded beam showed better photon flux, speed and signal quality, with a clear gain over the standard mode with a monochromator. Short-lived features hidden before became visible. The authors lay a base for sharper studies of chemical and biological dynamics.
