The reflectometer ADAM at ILL - Perspectives for an angle dispersive instrument — •Max Wolff, Kyrill Zhernenkov, and Hartmut Zabel — Lehrstuhl für Festkörperphysik/EP IV, Ruhr-Universität Bochum, 44780 Bochum, Germany

The angle dispersive neutron reflectometer ADAM at the ILL offers high flux combined with an excellent Q resolution and full polarization analysis with privileged access for the german user comunity. During the last ten years nearly all components of the instrument have been modified to remain a state-of-the-art instrument. We will give a brief overview on the most recent improvements and most outstanding results obtained during the last years.

To further improve the performance of the instrument we plan to reconstruct the reflectometer. ADAM-2 will again be an angle dispersive reflectometer. The challenging task is to offer both options high resolution and high intensity on a monochromator instrument. To account for this we plan to use an intercalated graphite monocromator in combination with focusing guide elements. In addition the instrument will feature different recent and new developments like, grazing incident small angle scattering, spherical polarisation analysis and pump probe experiments. Combined with an improved infrastructure for sample preparation and environment unique possibilities for the investigations of magnetic thin films, self assembling layers and biological systems will be provided due to the high flux, the low background and excellent polarization analysis.
