Björn Wiik lived in his home town Bruvik until he began his physics studies at Germany's
Technical University of Darmstadt . In 1965, he got his doctorate degree there. Two years later he began working at theStanford Linear Accelerator Center inMenlo Park, California . In 1972, Wiik returned to Germany, to the German Electron Synchrotron (DESY ) inHamburg where, four years later, he was appointed lead scientist.In 1978, Wiik and his collaborators began using DESY's newly commissioned PETRA electron-positron storage ring to look for hard-gluon
bremsstrahlung events that would provide experimental support for the existence and role of gluons in mediatingstrong interactions amongquarks . Wiik and his team soon observed and reported a type of event never described before: three particle-jets whose momenta lay in a plane. These results, widely believed to represent the after-effects of two quarks plus a gluon, were soon confirmed by many other groups. In 1995, theEuropean Physical Society awarded its Prize for High Energy and Particle Physics to four physicists representing theTASSO Collaboration (Paul Söding, Bjørn Wiik, Günter Wolf, and Sau Lan Wu) for demonstrating the existence of the gluon.

Retrieved on2008-05-28 .]Already during his stay at SLAC, Wiik had proposed a new type of particle accelerator, which would be based on colliding a beam of
protons with a beam ofelectrons . In 1980, this idea took concrete form with the creation at DESY of the hadron-electron ring facility HERA). Wiik was also responsible for proposing and overseeing the implementation of a superconducting linear accelerator for Tera-electron-volt energies, TESLA.
