X-rays

X-rays are a type of electromagnetic radiation with a wavelength between 0.01 and 10 nanometres. X-rays offer an important method for investigating the atomic structure of crystalline materials and nanometre-scale structures. Distant galaxies and clusters can be detected by the X-rays they emit.

    A high-intensity attosecond X-ray free-electron laser, meeting the demands of attosecond science for research on the sub-femtosecond-timescale quantum-mechanical motion of electrons in molecules and solids, is now available for attosecond pump–attosecond probe experiments in the soft X-ray region.

    Increased bandwidth and fluctuations are hurdles on the path towards generating intense fully coherent X-ray free-electron laser output. A recent experiment at FERMI Trieste demonstrated that these difficulties can be overcome by an approach called echo-enabled harmonic generation.

    European accelerator-based X-ray facilities came together in 2017 in a consortium that will use their combined expertise to accelerate discoveries, secure funding and guide policy. A year and a half later, the chair of the consortium Helmut Dosch reflects on the ambition and opportunities of this type of cooperation.
