Zusammenfassung: | In this study, we developed a user-friendly automatic powder diffraction measurement
system for Debye–Scherrer geometry using a capillary sample at beamline BL02B2 of
SPring-8. The measurement system consists of six one-dimensional solid-state (MYTHEN)
detectors, a compact auto-sampler, wide-range temperature control systems, and a gas
handling system. This system enables to do the automatic measurement of temperature
dependence of the diffraction patterns for multiple samples. We introduced two measurement
modes in the MYTHEN system and developed new attachments for the sample environment such
as a gas handling system. The measurement modes and the attachments can offer in
situ and/or time-resolved measurements in an extended temperature range between
25 K and 1473 K and various gas atmospheres and pressures. The results of the
commissioning and performance measurements using reference materials (NIST CeO2
674b and Si 640c), V2O3 and Ti2O3, and a
nanoporous coordination polymer are presented. |
