The reflectometer SuperADAM is an angle dispersive fixed wavelength instrument with two resolution options utilising different monochromators. It combines high flux due to focussing monochromators with options for high Q resolution and polarisation analysis.
Main description
The SuperADAM reflectometer is a CRG instrument operated as a German-Swedish collaboration. SuperADAM has 2 instrument modes to allow for different wavelength resolution and polarisation options. The 2 monochromators both deliver 4.4Å beams to the sample at different guide take-off angles.
The first of these is the vertically focussing HOPG monochromator as found with the original ADAM instrument. This mode of instrument operation offers high resolution and the possibility of polarised neutron beams with typical polarisations of around 98.6%.
The second monochromator is currently in development. This vertically focussing intercalated graphite monochromator offers a lower resolution and an improved flux over HOPG. After further tests in the November/December 2011 cycle this option should be available to users from Spring 2012.
A more detailed description of the instrument specifications can be found on the characteristics page.
Proposals for SuperADAM should be submitted via the visitors club website. CRG access for German users should be arranged through the group leader in Bochum (hartmut.zabel(at)rub.de). Swedish users should follow the instruction found here.
SuperADAM is funded by BMBF (German funding) and the Swedish Research Council, VR (Swedish funding).
