The reflectometer SuperADAM is an angle dispersive fixed wavelength machine which will offer two operation modes. A high flux option with a focussing intercalated graphite monochromator and a high resolution mode with a focussing pyrolytic graphite monochromator. The high flux option will be available in June 2010. An optional polarization and polarization analysis setup can be used for studies of magnetic layered systems. A two dimensional position sensitive detector allows time efficient collection of off-specular data. With a maximum scattering angle of about 95° of the detector arm Q-values up to 2.1 Å-1 can be reached for complementary measurements probing small length scales.
Specialised sample environment can be provided including a cryo-furnace and an electromagnet or cryomagnet.
Being a CRG-B instrument, 30% of the beamtime are made available via the standard ILL proposal scheme.
SuperADAM is operated by the Institut für Experimentalphysik/Festkörperphysik of the Ruhr-Universität Bochum headed by Prof. Dr. Hartmut Zabel, and by the Devision for Material Physics of the Uppsala University headed by Prof. Dr. Björgvin Hjörvarsson and Prof. Dr. Adrian Rennie.
Since ADAM is co-funded by the German BMBF additional beamtime is made available to the German community within the 'Verbundforschung'.
