New options for MIRA at the FRM-II

MIRA is a versatile instrument for very cold neutrons (VCN) using neutrons with a wavelength λ>8 A. The flux at the sample position is 5.105 neutrons/(cm2s) unpolarised. It is situated at the cold neutron guide NL6b in the neutron guide hall of the FRM-II. As the instrument set-up can be changed quickly, MIRA is ideally suited as a testing platform for realizing new instrumental set-ups and ideas. In particular, MIRA is unique in its possibilities of combining different neutron scattering methods as: Polarized or non-polarized reflectometry, spherical Polarimetry, polarized or non-polarized small angle scattering (SANS), classical NRSE (Neutron Resonance Spin Echo) setup as well as using the MIEZE principle. A new polarising multilayer monochromator was taken into operation. This allows now full polarisation analysis, 3D-polarimetry and MIEZE measurements. Selected experiments using these new options are presented here
