The department “Neutron Scattering” of the Institute of Materials Research, materials physics is based at the Heinz Maier Leibniz Zentrum MLZ in Garching near Munich. We operate the GEMS instruments:

- materials science diffractometer STRESS-SPEC together with the Technische Universität München (TUM) for the analysis of strains, textures, and phases;

- neutron small angle scattering instrument SANS-1 – also in partnership with the TUM – for the measurement of nanostructures in bulk samples;

- the reflectometer at horizontal surfaces REFSANS for the characterisation of nanostructures at interfaces. These instruments cover the characterisation needs of a broad user community we support during their measurements at our instruments.

We also operate a Materials Science Laboratory together with TUM, equipped with state-of-the-art facilities (i.a., X-ray diffractometer, calorimeter, optical microscopes) available for our users for their sample preparation and pre-characterisation.

In addition to our main activity, operating large-scale instruments and supporting our users suring measurements and data analysis, we also persue our own research projects. Our activities are embedded into the Helmholtz MML programme.

The department “neutron scattering” uses neutron diffraction methods and makes them available for external users, in particular:

• strain analysis
• texture measurements
• phase determination
• analysis of nanostructures in the bulk of samples
• analysis of nanostructures at interfaces

We use neutrons at the Heinz Maier-Leibnitz Zentrum (MLZ) in Garching near Munich. For the pre-characterization of samples, there are also lab instruments available.
Our neutron scattering experiments are complementary to the corresponding X-ray experiments as neutrons do not only offer a great penetration depth into most materials, they also highlight different elements than X-rays.
The beamtime at our instruments is distributed to users via the MLZ proposal system (https://user.frm2.tum.de/).

Users from academia and industry can choose between a collaborative and proprietary mode of access. In the collaborative mode, the beamtime is completely free of charge, in exchange the results have to be published in scientific journals. Alternatively, beamtime can be bought in the propietary mode (please contact us concerning prices), the results of these measurements will be treated confidentially.
