Structure research

Instruments to investigate atomic positions, lattice spacings and magnetic structures are defined as single crystal diffractometers, including protein crystallography and powder diffractometers including engineering diffractometers. They mainly use a fixed, monochromatic incoming wave length with the exception of POWTEX, which utilises a wave length band of pulsed neutrons. Common to these instruments is the analysis of scattered neutrons which does not include an energy separation. An optional analyser might separate elastic from otherwise diffuse inelastic scattering; the spectroscopic measurement of atomic movements is, however, not the focus of these instruments. If further developments are undertaken on the instrument MIRA, this might shift it to the spectroscopy section in the future, taking into account the optional analyser and the MIEZE setup. On the other hand, the DNS spectrometer is well-suited to investigate diffuse elastic scattering, i.e. for structure research.
