This course is suitable for researchers working in both academia and industry that want to learn how to carry out powder diffraction refinement.
Participants are expected to be familiar with basic X-ray diffraction theory. To aid in this, and ensure a common base of knowledge, please watch the lecture videos available in the Registered Participants Area.
Download and install GSAS-II software (available in the Registered Participants Area) on the laptop you will bring to the course, and ensure that this is working.
Learning objectives:
-
To understand the basics of powder diffraction refinement theory and how it affects how we carry out a refinement
-
To be able to set up and run a powder refinement (using the GSAS-II software)
-
To be aware of different types of powder refinement fits (Rietveld, Pawley, Le Bail) and how they might be useful
Various topics will be discussed including lattice parameter determination, instrument parameter files, crystallite size determination, quantitative phase analysis, and different refinements methods.
Participants on the course will be provided with:
-
Complete set of course notes covering the theory of powder diffraction refinement
-
Access to a series of video lectures on X-ray powder diffraction theory
-
Walk -through guide on setting up a refinement in GSAS-II
-
Series of example refinement problems with suitable guidance
