500 _ _ |a additional grant name: BMBF 05K19PA2: Entwicklung und Optimierung von Hochdruckprobenumgebung für polarisierte und unpolarisierte Neutronendiffraktion und - spektroskopie an den Instrumenten HEiDi, POLI, MIRA und DNS am Heinz Maier-Leibnitz Zentrum.
520 _ _ |a Single crystal neutron diffraction, especially with hot neutrons, supports various grand challenges in research as well as method developments. In regard to this the instrument HEiDi at the hot source of FRM II offers features like fast and high quality Bragg data collections up to very large Q (> 20/Å for λ=0.56Å) within a broad temperature range (2K < T < 1300K) and offers since 2019 also high pressure experiments (p < 10 GPa).The full exploitation of these options and the safe support of 24h/7d user operation requires a highly flexible and autonomous software for device control and data acquisition. Accordingly, the HEiDi software provides various routines in order to determine and to adopt in operando for the best possible parameters for sample centering, sample orientation and reflection collection or to avoid collisions and shading during running experiments. Other routines simulate the experiment in terms of expected beam time or completeness for optimized planning of the experiment. Recent activities focus on (i) porting the existing software and its features to a NICOS-based control system including the implementation of extended typical single-crystal multi-parameter measurements and (ii) integration of tools for the extraction of intensities from a new Li scintillator based area detector, an important step also for potential future applications such as PDF studies on disordered systems up to high Q.[1] M.
