A research team from European XFEL and DESY has achieved a breakthrough in X-ray science by generating high-power attosecond hard X-ray pulses at megahertz repetition rates. These pulses, with energies exceeding 100 microjoules and durations of a few hundred attoseconds, enable advanced studies of ultrafast electron dynamics and non-destructive atomic-level measurements. Jiawei Yan, a physicist at European XFEL and the lead author of the study, highlighted that these unique X-rays allow for damage-free measurements of structural and electronic properties.
