The (10.6 X 10.6)m2 storage ring in Aarhus is now operating both with ions (positivelnegative) and with electrons (E,, = 580 MeV) for production of synchrotron radiation (SR). In the ion case more than 30 ions and clusters have been stored lowest energy 5 keV. Equipment for laserand electron-cooling is installed. Until now three SR-beamlines have been installed: one with a Zeiss plane grating m...
