International School on Introduction in the Rietveld structure refinement

Introduction to the theoretical background of the Rietveld method and principles of crystal structure refinement from powder diffraction data

Sofia, Bulgaria, 28 September - 3 October 2015

This six day long school aims to introduce participants to the way the information about crystal structure and sample microstructure is contained in X-ray powder diffraction patterns and how to get use of it.

The school provides a set of lectures, devoted to the main aspects of crystal structure description and fundamentals of powder diffraction. Main concepts, that Rietveld structure refinement is based on, will be covered as well.

Practical sessions are designed to initiate and promote basic skills for working with powder diffraction data and respective data treatment software. Tutors will be on disposal to help participants in the course of training.

Discussions will be focused on:

  •  Requirements for the quality of data collection and powder diffraction patterns;

  •  Structure refinement strategies;

  •  Detecting and characterization of microstructural aspects of studied sample;

    •  crystallite size and shape;

    •  residual stress and strain;

An introduction to structure solution from powder diffraction data is envisaged as well.
