ANKA-status of the 2.5 GeV synchrotron light source at Forschungszentrum Karlsruhe

ANKA, a 2.5 GeV synchrotron light source will be built within the next three years at the Research Centre Karlsruhe, Germany. This source is dedicated to the fabrication of microstructures (LIGA-technique) and X-ray analysis. With four double-DBA structures, a magnetic field of 1.5 T and a circumference of 110.4 m, an emittance of 39 nm·rad can be reached. ANKA has four long (6 m) straight sections for the installation of insertion devices. Additional four short (2.2 m) straight sections host the injection scheme, four ELETTRA-type cavities (two cavities per section) and one short insertion device. The RF power will be provided by two 250 kW klystron. The pre-acceleration will be done with a 22-50 MeV linac or microtron. As injector a 500 MeV booster synchrotron with a repetition rate of 3 to 10 Hz is foreseen. The ramping from 0.5 GeV to 2.5 GeV will be done in around one minute. Eleven out of thirty-two available bending magnet radiation ports will be equipped with beam lines in the first phase
