Polarised neutron reflectometer with X-ray option
This instrument is focussed on cold neutrons. All parameters given here are valid during the current operation of FRM II. Please get in touch with the instrument team well in advance for all further details (length of experiment etc.).
The neutron/ X-ray contrast reflectometer NREX is designed for the determination of structural and magnetic properties of surfaces, interfaces, thin films and heterostructures.
A focusing multiblade monochromator allows for measuring small area (20 mm2) samples with high polarisation in a dynamic range of six orders of magnitude. For larger samples and a non-polarized beam more than seven orders are feasible. A horizontal alignment of the sample allows for performing (a) GISANS and GIND and (b) in-situ X-ray experiments. For the latter an optional X-ray reflectometer is mounted perpendicular to the neutron beam. Simultaneous neutron/ X-ray experiments allows for effective studies of irreversible processes and sensitive samples.
A (polarised) neutron reflectometry alone and in combination with X-ray reflectometry provides information about spatial distribution of chemical elements and isotopes and magnetic moment. A selected list of examples:
