Layout of a single angular segment (side view), the distance between the analyzers at the bottom (purple, mounted on holders) and the detectors at the top (illuminated length marked in red) is 400 mm. Neutrons scattered by the sample enter the segment from the left as indicated by the arrow. The distances of the analyzers to the sample are 1050 mm, 1220 mm, 1387 mm, 1552 mm and 1732 mm, respectively. This corresponds to vertical angular acceptance angles of ±1.40°, ±1.10°, ±0.89°, ±0.75° and ±0.63° for an ideal point-like sample, while the horizontal acceptance angles are ±0.55°, ±0.47°, ±0.41°, ±0.37° and ±0.33°, respectively.
