In the beginning of the development the synchrotron and storage rings generated only
radiation in the region of longer wave lengths starting at about 1 nm. The first only
successful measurements with synchrotron radiation were performed in 1963 when R.P.
Madden and K. Codling1 determined the absorption of low energy X rays by gases by
using a synchrotron operating at 0.18GeV at the National Bureau of Standards.
Sources for radiation in the range of the smaller wave lengths down to about 0.1 nm are
the synchrotron radiation DESY completed in an the storage ring DORIS completed in,
both at Hamburg. The synchrotron radiation of DORIS is presently used by two
laboratories, the outstation of EMBL (European Molecular Biology Laboratory) and the
HASYLAB (Hamburger Synchrotron Laboratory). At EMBL studies of wide angle and
small angle X ray scattering of biopolymers and synthetic polymers are performed. At
HASYLAB, facilities for VUV-measurements, X-ray topography, a 2-cicle and a
5-circle goniometer and so on are available. A small angle scattering beam line for
studies of rapid structural and morphological changes in polymer since will operational
in 1984.2
Further storage rings which have a research program similar to DORIS are the SRS at
DARESBURY in Great Britain and the Photon Factory in Japan. For studies in the
VUV-region and especially industrial applications like X-ray lithography, the storage
ring BESSY at Berlin is used.
Finally we note a proposal for an European Synchrotron Facility (ESRF)3 with a 5GeV
storage ring which can accommodate about 14-15 multipole wigglers and 15 undulators.
