ANKA- OPERATION AND FUTURE PLANS

ANKA, a 2.5 GeV storage ring for synchrotron radiation in Karlsruhe, delivers beam to ten bending magnet beamlines: an infrared (edge effect), three LIGA and several X-ray beamlines (absorption, diffraction, fluorescence, topography, protein crystallography and surface diffraction). Generally, there is one injection per day with a current of around 200 mA and a lifetime of more than 20 hours. Several machine improvements have been done during the last year: calibration of the BPMs by a Beam Based Alignment procedure, improvement of the orbit correction, studies of the cavitys HOM and introduction of new filling patterns. Unfortunately, an accident in one beamline has contaminated the storage ring vacuum chamber with Krypton. The system is slowly recovering, five weeks after the accident a beam current of 150 mA with a lifetime of 16 hours was stored. In the near future two insertion devices are going to be installed at ANKA: one planar undulator for soft X-rays and a wiggler for an environmental beamline A superconductor undulator is as well under development [1].
