Description
DNS is a multipurpose diffuse neutron scattering instrument. It supports polarized powder and single-crystal diffraction studies and also enables neutron time-of-flight (TOF) spectroscopy measurements when an optional disk chopper is inserted into the neutron beam between the polarizer and the sample. The instrument is particularly powerful for investigating magnetic correlations in complex magnetic materials and exotic quantum magnets, as well as low-energy magnetic excitations when operated in a time-of-flight mode.
Data reduction is an essential stage of the DNS data processing pipeline. It involves removing contributions from the instrument and its environment from the measured raw data, followed by the transformation of the corrected data into physically meaningful $(Q, E)$ space in terms of the scattering vector $Q$ and energy transfer $E$.
In this work, we present DNS Reduction - a new graphical interface that has recently been fully integrated into the open-source Mantid software project. The interface enables instrument scientists and users of the DNS instrument at MLZ to reduce their data in a user-friendly and reproducible way. It implements a set of data-reduction algorithms for the main types of DNS experiments, including polarized powder diffraction, TOF inelastic scattering on powder samples, and polarized single-crystal diffraction. It is intended to replace the legacy DNSplot software at the instrument.
