Accelerators for photon science

• PETRA III: DESY operates one of the brightest storage ring X-ray radiation sources in the world.

• PETRA IV: The storage ring PETRA is to be expanded into the world’s most powerful synchrotron radiation source.

• FLASH: The free-electron laser generates ultrashort-pulse X-ray laser light.

• FLASH2020+: The upgrade project makes the FLASH free-electron laser even more flexible and powerful.

• European XFEL: DESY is the main shareholder and operates the accelerator of Europe’s big X-ray laser.

Particle physics

• LHC: The Large Hadron Collider at the CERN research centre near Geneva is the world’s most powerful accelerator.

• Belle II: The experiment at the SuperKEKB accelerator in Japan is used for research with B mesons.

• ALPS II: The experiment searches for extremely light particles.

• BabyIAXO: The prototype for the International Axion Observatory (IAXO) will search for extremely light particles from the sun.

• MADMAX: The experiment is intended to explore the dark matter in our galaxy.

• LUXE: The experiment is designed to test the theory of quantum electrodynamics.

Astroparticle physics

• H.E.S.S.: The observatory in Namibia explores cosmic gamma rays.

• CTAO: The observatory will investigate high-energy gamma rays from space.
