The first five chairmen of the DESY directorate, photographed in 1993. From left: Herwig Schopper (1973–80), Wolfgang Paul (1971–73), Willibald Jentschke (1959–70), Volker Soergel (1981–93) and Bjørn Wiik (1993–99). (Courtesy DESY.) md5:086e069e7a62cf806d8e0850e3abb3b8	618.2 kB	Preview Download
An event recorded by the ARGUS detector at the DORIS storage ring shows the decay of the Υ(4S) resonance into a pair of B mesons, identified by their decay. This is evidence of B–B– mixing. (Courtesy DESY.) md5:0ffdf56f97374000b38c0d35967395c8	197.8 kB	Preview Download
A three-jet event, registered at the PETRA storage ring; such events were a direct evidence for the existence of gluons. (Courtesy DESY.) md5:0e53acf69dda438c41d2ec396a7a3278	169.4 kB	Preview Download
A deep inelastic electron–proton scattering event, recorded by the H1 detector at HERA. The proton beam comes from the right, the electron beam from the left. The electron is back-scattered off a quark inside the proton and emerges to the left upwards. The quark is knocked out of the proton and produces a shower at the lower left.

A view inside the 6.3 km tunnel of HERA shows the superconducting magnets – used to guide the proton beam – installed above the normally conducting magnets of the electron ring. (Courtesy DESY.) md5:4c9e12b1bff790518868bb4e000dbb06	465.1 kB	Preview Download
Measuring station in the experimental hall of the new PETRA III synchrotron radiation source at DESY – one of the most brilliant storage-ring-based X-ray sources in the world. (Courtesy Dominik Reipka, Hamburg.) md5:b5168d5854307e9938023b3ecbada4a9	1.2 MB	Preview Download
The 30 m-long undulator of the FLASH free-electron laser at DESY, the only such facility to produce high-intensity, ultrashort radiation pulses in the vacuum ultraviolet and soft X-ray wavelength range down to 6.5 nm.

The new CMS and ILC control rooms at DESY allow the operation and data-taking of CMS to be monitored as well as ILC test experiments at CERN and Fermilab to be run remotely from Hamburg. (Courtesy Barbara Warmbein, DESY.) md5:a67ff0fdaf4c75fd16fb0fdf2ff7002d	482.1 kB	Preview Download
