ASTRID. The Aarhus dual purpose storage ring for positive/negative ions and electronsE. Uggerhøj
Institute for Synchrotron Radiation, Aarhus University, 8000 Aarhus C, Denmark
The (10.6 x 10.6)m2 storage ring in Aarhus is now operating both with ions (positive/negative) and with electrons (Emax = 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 laser- and electron-cooling is installed. Until now three SR-beamlines have been installed : one with a Zeiss plane grating monochromator (SX 700) and a complete UHVequipment for surface physics. The second one includes a new spherical grating monochromator (SGM) for atomic physics equipment. The third is dedicated to an imaging x-ray microscope. Thus, today ASTRID is the scene of a wide range of research using SR from infrared to x-rays and ions of many types. For the ion case an EBIS ion source for injection of multiply charged ions is under construction, together with a new detection facility for charge and mass detection of collision fragments. For SR a VUV undulator is under construction.
