Abstract

MIRA is the beam line for very cold neutrons (7.7 Å<λ<30 Å) at the new FRM-II neutron source. It can be operated as a classical reflectometer, working in the θ-2θ-scan mode and a horizontal reflection geometry. A q-transfer range of 7.0 × 10 -4 Å -1 <q<1.1 Å-1 can be accessed. A flux of 2.0 × 106 neutrons/cm2 s at the sample is aimed for. We also plan to use a multilayer polariser and an analyser, in order to perform polarised neutron reflectometry. Furthermore, the instrument will be used for the development of new techniques. Here, the extension of the conventional polarised neutron reflectometry to 3D polarimetric reflectometry and phasometric reflectometry is foreseen as a future option of the instrument.
