CRG - Advanced Reflectometer for the Analysis of Materials

The reflectometer SuperADAM is an angle dispersive fixed wavelength machine which combines high flux due to a focussing monochromator with a high Q resolution.

SuperADAM is a redesigned version of ADAM. This CRG reflectometer for the analysis of materials is an angle dispersive fixed wavelength machine with horizontal scattering plane. The new instrument has two operation modes. A high flux option (focussing monochromator made of intercalated graphite), mainly dedicated for soft matter research, and a lower flux option but with an improved Q resolution. It offers unique possibilities especially for measurements on magnetic samples due to the high resolution and the possibility of high polarisation and an accurate polarisation analysis.

SuperADAM offers extended capabilities making it possible to envision new types of experiments.

The drawing shows the heavily shielded position sensitive detector (300 x 300 mm), but a single detector is available if needed.
