Disordered Materials Diffractometer

A view of the fan-like neutron-detector

The detector assembly is a array of nine 1D position sensitive detectors with an angular resolution of 0.125º. The available 2θ-range is 1.5º to 140º. Because there are 7º in between two detectors, 2-positions scans are required to produce a complete diffraction pattern up to 135º. For a complete diffraction pattern up to 140º at least 3 positions are required.
