Abstract
At BESSY II the first quasi-periodic hybrid type undulator has been installed. The magnetic structure has been optimized for higher order suppression and simultaneously for high flux in the (shifted) 5th harmonic to provide an useful energy range between 20 and 500 eV. At smallest gap of 15 mm the device operates as a wiggler with a K-value of 16.
