Figure 4: Schematic of the HIPPO general purpose neutron time-of-flight diffractometer at LANSCE [77, 78]. The red areas in the schematic are the 53 detectors panels, arranged on five rings with nominal diffraction angles of 144°, 120°, 90°, 60°, and 40° (left to right in this schematic) around the incident beam direction. The 144° panels of the same azimuth angle are typically combined together, resulting in 45 histograms. The tank in the center of the instrument has a volume of about 1 m3 and can accommodate various sample environments. The large detector coverage allows to either probe 45 sample directions simultaneously for texture measurements [208, 209] or when data is appropriately merged to utilize the resulting short count times for kinetics studies.
