- BESSY
The Berliner Elektronenspeicherring-Gesellschaft für Synchrotronstrahlung m. b. H. ("BESSY") is a research establishment in
Berlin operating actually the only German 3rd generation synchrotron radiation facility BESSY II. The supply of synchrotron light is support for science and industry. Of particular significance are the activities of the institutional users Hahn-Meitner-Institut, Max-Planck-Gesellschaft, Federal Institute for Materials Research and Testing (BAM), and cooperating research groups. Owing to the radiometry lab of the Physikalisch-Technische-Bundesanstalt, BESSY is the European calibration standard for electromagnetic radiation.

In 2008 BESSY was consolidate with the Hahn-Meitner-Institut (new name: "Helmholtz-Zentrum Berlin für Materialien und Energie GmbH"). BESSY lefts therefore the
Leibniz-Gemeinschaft and join to theHelmholtz-Gemeinschaft .BESSY I
This facility for 66,5 Million
Euro was operating from 1981 to 1999 in Berlin-Wilmersdorf. In this synchrotron electrons with energies from 200 to 800 MeV where used and the storage ring had an circumference of ca. 60 m.The component parts of the BESSY I machine generously donated to the SESAME project by the German Authorities have been shipped from Germany and have arrived in Jordan where they are being kept in trust for the project by the Jordanian Ministry of Education.

BESSY II
The storage ring of BESSY II has an circumference of 240 m providing 46 beam lines and offers a multi-faceted mixture of experimental opportunities at undulator, wiggler and dipole sources with excellent energy resolutions. The combination of brightness and time resolution enable both femtosecond time and picometer spatial resolutions.
