Reflectometer
Reflectometry Station
The versatile 11 axes UHV-reflectometer is a permanent end station of the Optics Beamline delivering UV and XUV radiation. It is located in a clean-room hutch at DIP 1.1. The samples are adjustable within six degrees of freedom, and the reflectivity can be measured at all incidence angles for both s- and p- polarisation geometry.
Selected Applications:- at-wavelength metrology on XUV optics (diffraction gratings, ML or single coated mirrors, filters and etc.)
- Soft X-ray/XUV reflectometry (SXR, XRR)
Methods

Refelctomenter is equiped by LoadLock system with 5 slots for sample holders. This anables fast in-vacuum change for sampls with sizes in limits of 60mm * 40mm * 10mm (l*w*h).
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.
