Geometry of the experimental setup. Top: photograph of the specimen assembly on the ENGIN beamline (the forerunner to ENGIN-X) at ISIS. The sample is held within the Instron load frame at 45° to the incident neutron beam. The neutron detectors are at ±90° to the incident beam. Bottom: a schematic plan view of the experimental arrangement. In this geometry the detector to the right of the sample detects neutrons with scattering vectors parallel to the loading direction, while the detector to the left of the sample detects neutrons with scattering vectors normal to the loading direction. |
