Abstract :
The soft X-ray monochromator beamline installed at an elliptical undulator at BESSY-II is discussed. A technical description of the undulator and the main elements of the beamline is given. The APPLE-II type magnetic structure of the undulator is a pure permanent magnet design and allows four different modes of operation: circular polarization, horizontal and vertical polarization, and linear polarization under various angles. The beamline optics was designed to cover the soft X-ray energy range from 200 up to 2000 eV, and the plane grating monochromator has three different gratings which can be selected by a lateral translation inside the UHV vacuum.
