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 structur
e of the undulator is a pure permanent magnet design and allows four differ
ent modes of operation: circular polarization, horizontal and vertical pola
rization, 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. (C) 2001 Elsevi
