Extended SX-700 type monochromator combining normal and grazing incidence optics for a new undulator beamline at SLS

The surfaces and interfaces spectroscopy (SIS) beamline at the Swiss Light Source (SLS) covers the photon energy range from 10 to 800 eV. The beamline will start operation in summer 2001. The optical design is based on a SX-700 type plane grating monochromator extended by a normal incidence light path to provide high resolving power and harmonic rejection also at low photon energies.
