SwissFEL Achieves Ultralow-Temperature X-ray Observation of Quantum States
Researchers at the Paul Scherrer Institute (PSI) in Switzerland recently reported that the Cristallina experimental station of the Swiss Free-Electron Laser (SwissFEL) can now observe quantum states that only emerge at extremely low temperatures using X-ray scattering at temperatures close to absolute zero.

With the help of a custom-built cryostat connected to the beamline (far left), quantum states can now be studied at extremely low temperatures.
