ANKA-Status of the 2.5 GeV Synchrotron Light Source at FZK, Karlsruhe Germany.

ANKA, a 2.5 GeV synchrotron light source will be built within the next three years at the Research Center 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 103.2 m, emittances of 45 nmrad can be reached. ANKA has two long (5.8 m) and two short (3.8 m) straight sections. One will be used for injection; the other three are available for insertion devices. Four 500 MHz cavities of the ELETTRA-type will be distributed around the ring, one in each center of the double-DBA structure. The current will be 200 mA in a first phase. The RF power will be provided by one 250 kW klystron. 14 out of 32 available bending magnet radiation ports will be equipped with beamlines in the first phase. The preacceleration will be done with a 22-50 Mev linac or microtron. As injector a 500 MeV booster synchrotron with a repetion 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.
