This soft x-ray bending magnet beamline is equipped with a Plane Grating Monochromator operated in collimated light (collimated PGM). It uses the SX700-1 monochromator equipped with two diffraction gratings 150l/mm for low and 1200 l/mm for high energy ranges. The beamline is optimised for operation with moderate energy resolution but at very high specular purity and efficient stray light reduction provided by a 4-mirror High order suppressor (HIOS), a Filter and Slit Unit (FSU) and additional system of adjustable apertures over the beamline.

The beamline is permanently coupled with versatile 11-axis UHV reflectometer. The reflectometer is optimized for operation with small test sampleas as well as for characterisation of real live-sized optical elements. The whole experiment is located in a clean-room hutch providing rather safe for tested contamination sensetive optics.
The setup is primarily dedicated to the in-house R&D in XUV optics and at-wavelength metrology of in-house produced diffraction gratings. It is also available by user-proposals with possibilty of a short-term request is specific cases.
