STATUS OF THE SYNCHROTRON LIGHT SOURCE DELTA

Since 1999, the Dortmund 1.5 GeV electron storage ring DELTA was continuously extended. The facility serves universities and industries as a source of synchrotron radiation on a regional level. By now, DELTA, operated for 3000 hours per year, has reached a reliability comparable to other facilities in the world. Improvements have been achieved in the installation of the beamlines. At present, two undulator beamlines and several dipole beamlines are in operation. The 5.3 T superconducting asymmetric multipole wiggler (SAW) serves three beamlines in the hard X-ray regime with circular polarized radiation. Also the accelerator physics research program has been promoted. The vacuum system was revised during the last year to provide extra space for test sections and additional diagnostics. Substantial progress was achieved by SVD based orbit correction as well as detailed coupled bunch mode (CBM) studies. Future developments for machine improvements, such as a DSP-based fast local orbit feedback and a frequent injection mode are in preparation.
