Europe's new X-ray laser delivers results: Scientists used the EuXFEL to reveal the structures of the tiniest proteins - [News]

The European XFEL, or EuXFEL— currently the largest X-ray free-electron laser in the world-produced its first light in May 2017. The facility, built in a 3.4-kilometer tunnel near Hamburg, Germany, was commissioned in September of last year. And August 2018 brought another milestone—the publication of the first scientific paper based on experiments with the laser, which the authors used to probe the 3D structures of protein microcrystals.
