ADD2016

School and Conference on Analysis of Diffraction Data in Real Space

Grenoble, 7 to 11 March 2016

 Co-organised by:
     
Institut Laue-Langevin (ILL) and The European Synchrotron (ESRF)

 

Introduction

Although the structures of disordered systems such as liquids and glasses have been studied for over 50 years via Fourier transformation of diffraction data into real-space, it is only over the past decade or two that the use of real-space data analysis in diffraction has become increasingly popular for structural studies of crystalline systems showing some disorder.  In powder diffraction for example, Pair-Distribution Function (PDF) analysis of total-scattering data is sensitive to local static and dynamic disorder, and has thereby demonstrated complementarity to the well-known Rietveld refinement used to determine the time- and space-averaged structure of crystalline systems.

Real-space analysis of diffraction data deals with general structural concepts such as atomic distribution functions and structural correlation lengths, and now employs standard formulae common to neutron, x-ray and other diffraction techniques.  It therefore facilitates a synergetic convergence of hitherto largely disjoint communities: liquids/glasses diffraction and crystalline powder diffraction.

Building on the success of our previous ADD workshops in Grenoble (ADD2011 of 12-14 October 2011, ADD2013 of 18-22 March 2013), the ADD2016 School+Conference will start Monday afternoon 7 March 2016 and finish Friday afternoon 11 March, a 4-day programme which includes a 2-day School part followed by a 2-day Conference part, basically the same format as ADD2013.  The scientific scope of ADD2016 will again include single-crystal diffuse scattering, for which the School proposes a 5th hands-on tutorial for training in using the Yell software, in addition to the hands-on tutorials for DISCUS, PDFgui, RMCProfile and EPSR that were offered for ADD2013.

 

Aim and scope

The ADD2016 School and Conference aim to deepen the understanding and to further the training of the various communities working on real-space data analysis for neutron, x-ray and other diffraction techniques. Fourier transformation of diffraction data into real-space, traditionally used for the structural determination of liquids and glasses, has recently seen increasing development in the field of crystalline powder diffraction where it complements the well-known Rietveld refinement of diffraction data. Real-space analysis of total-scattering data is sensitive to local, possibly time-dependent, structural disorder, and therefore enjoys a wide field of application, in particular to nano-structured materials. The 2-day school includes educative lectures and hands-on tutorials as concerns the experimental techniques and software available for real-space analysis of diffraction data. Inmediately after the school, a 2-day conference begins, where presentations on the various scientific areas of application will be given.
