The HASYLAB (Hamburger Synchrotronstrahlungslab or, "Hamburg Synchrotron radiation Laboratory") is used for research with synchrotron radiation at DESY. It was opened in 1980 with 15 experimental areas (today there are 42). The laboratory adjoins to the storage ring DORIS in order to be able to use the generated synchrotron radiation for its research. While in the beginning DORIS served only one third of the time as a radiation source for HASYLAB, since 1993 all its running time is available for experiments with synchrotron radiation. On top of the 42 experimental areas DORIS provides, there are also three test experimental areas available for experiments with high-energy radiation generated with the storage ring PETRA.
