Grazing Incidence Small Angle X-ray Scattering (GISAXS)

Detector positioning system

• An independent mounting sytem for the Pilatus 2M area detector
• Sample-detector distance variable from 1.5-3 metres
• The detector can also move both horizontally and vertically covering an angular range from the sample of up to ~20 degrees depending on distance from sample

GISAXS flight tube

• Provides an air-free path between the sample and Pilatus 2M detector for GISAXS measurements
• Helium-filled
• Mica entrance and kapton exit windows
• Two internal beamstops, for the direct and reflected beam, which can be moved remotely
• Entire tube can easily be swung out of the way to allow the diffractometer arm to be lowered for reflectivity or other measurements, if required
