The “A-Unit” is a D5005 base goniometer set up in θ-2θ mode and optimised for high quality powder data collection. It is fitted with a focusing primary monochromator and 2.5° Soller slits, giving well collimated monchromatic radiation. It is thus especially suitable for the collection of data for structure solution and/or Rietveld refinement, and for long d-spacing materials. Due to the tight and symmetrical line-shape characteristics of the instrument, it is also well suited for the investigation of strain and crystallite size effects.
Specifications:
- Bragg-Brentano geometry
