DESY develops, runs and uses accelerators and detectors for photon science and particle and astroparticle physics. It operates PETRA III, one of the world’s best synchrotron radiation facilities, and FLASH, the first free-electron laser for soft X-rays. In 2017, the European XFEL started user operation and set a new world record by generating the most intensive X-ray flashes in history.
DESY is currently planning what will be the world’s most powerful synchrotron radiation source: PETRA IV will act as the ultimate X-ray microscope for nanoresearch, extending X-ray views to encompass every scale, from atoms to millimetres.
