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