PETRA III: A New High Brilliance Synchrotron Radiation Source at DESY

DESY in Hamburg, Germany, has decided to reconstruct its 2.304 km long storage ring PETRA II into a third generation synchrotron radiation source starting 2007. The synchrotron source will operate at 6 GeV particle energy, 100 mA current and an emittance of 1 nmrad. In the first phase thirteen independent undulator beamlines will be available for user experiments.
