DESY, short for Deutsches Elektronen-Synchrotron, is a national research centre for fundamental science located in Hamburg and Zeuthen near Berlin in Germany. It operates particle accelerators used to investigate the structure, dynamics and function of matter, and conducts a broad spectrum of interdisciplinary scientific research in four main areas: particle and high energy physics; photon science; astroparticle physics; and the development, construction and operation of particle accelerators. Its name refers to its first project, an electron synchrotron. DESY is publicly financed by the Federal Republic of Germany and the Federal States of Hamburg and Brandenburg and is a member of the Helmholtz Association.

LINAC II and DESY II are electron pre-accelerators for the storage ring PETRA III, which, together with the free-electron laser FLASH, serves as a light source for photon science. Also shown is the European XFEL X-ray laser, which runs from the DESY campus to the town of Schenefeld in Schleswig-Holstein.
The superconducting resonators used in the linear accelerators of the free-electron laser FLASH and the European XFEL X-ray laser are processed and assembled in a cleanroom.
Hamburg, officially the Free and Hanseatic City of Hamburg, is the second-largest city in Germany, after Berlin, and 8th-largest in the European Union, with a population of over 1.9 million. The Hamburg Metropolitan Region has a population of over 5.1 million and is the ninth-biggest metropolitan region by GDP in the European Union.
