Physics with Neutrons 2015/2016

View on the reactor pool of FRM II. Cherenkov light is emitted from the burnt fuel element during exchange of fuel elements.

View in the neutron guide hall of MLZ.

Neutron scattering is an essential tool to adress a large variety of modern condensed matter physics problems. The range spans from questions in soft condensed matter, biology and life sciences over applied materials research and industrial applications to magnetism and strongly correlated electron systems. With FRM II at Heinz Maier-Leibnitz Zentrum (MLZ) being operational since 2004, one of the worlds leading neutron sources is located at the heart of the campus in Garching.

This lecture will give a solid introduction into the theory of neutron scattering. The instrumentation used for neutron scattering experiments will be introduced in detail. It will be demonstrated how neutrons can be useful for condensed matter problems with the help of examplary research done at MLZ. An extended visit at FRM II and its instrumentation is foreseen.
