Abstract

Abstract : A fast and medium‐resolution neutron powder diffraction option for `energy research with neutrons' (ErwiN) at the high‐flux FRM II neutron source at the Heinz Maier‐Leibnitz Zentrum (MLZ) is described. Abstract : The need for rapid data collection and studies of small sample volumes in the range of cubic millimetres are the main driving forces for the concept of a new high‐throughput monochromatic diffraction instrument at the Heinz Maier‐Leibnitz Zentrum (MLZ), Germany. A large region of reciprocal space will be accessed by a detector with sufficient dynamic range and microsecond time resolution, while allowing for a variety of complementary sample environments. The medium‐resolution neutron powder diffraction option for `energy research with neutrons' (ErwiN) at the high‐flux FRM II neutron source at the MLZ is foreseen to meet future demand. ErwiN will address studies of energy‐related systems and materials with respect to their structure and uniformity by means of bulk and spatially resolved neutron powder diffraction. A set of experimental options will be implemented, enabling time‐resolved studies, rapid parametric measurements as a function of external parameters and studies of small samples using an adapted radial collimator. The proposed powder diffraction option ErwiN will bridge the gap in functionality between the high‐resolution powder diffractometer SPODI and the time‐of‐flight diffractometers POWTEX and SAPHiR at the MLZ.
