DORIS III

For several decades, scientists have conducted research using the very intense light from the DORIS storage ring at DESY. DORIS has been in operation since 1974 – initially both for particle physics and for research with synchrotron radiation. In 1990 and 1991 the storage ring was expanded to make room for seven additional magnet structures, so-called wigglers and undulators. This modified machine, DORIS III, has been used exclusively as a source of synchrotron radiation since 1993.

The results obtained are impressive. Time and again, the scientists and engineers at DORIS were able to develop new methods and instruments and to achieve breakthrough results that opened new fields of research. In many cases, what began as a local test experiment developed into a successful experimental method that ultimately established itself worldwide as a standard method used in research and industrial applications. The range of the experiments extends from effective catalysts and precision analytical methods for determining pollutants to innovative active agents for medical applications and lightweight but stable new materials.
