Triple-axis diffractometry

In later chapters we shall give both the fundamental theoretical treatment necessary to understand the complex rocking curves that arise from complex stmctrrres, and the practical experimental details reqitired to measure them reliably and urrambiguously.

For normal high-resolution studies, the detector has a fairly large aperture, typically 5-25 mm. There are some applications for position-sensitive detectors for low resolution triple-axis diffractometry. These are in essence gas-filled... 

In this chapter we have seen the new dimension that triple-axis diffractometry and reciprocal space mapping bring to the characterisation of complex materials.

The rocking curve is broadened by various factors. To extract them it is necessary to apply triple axis diffractometry, an extension of RC analysis. The recent work of Metzger et al [41] shows how it is possible, using this technique, to estimate correlation lengths of columnar crystallites, dislocation densities and angles of rotational disorder.
