  ICDD Rietveld Refinement & Indexing Workshop

ICDD Rietveld Refinement & Indexing Workshop

Let Our Team of Experts Help You Take Your Skills to the Next Level

Powder pattern Indexing and Rietveld structural refinement techniques are complementary and are often used to completely describe the structure of a material. Successful indexing of a powder pattern is considered strong evidence for phase purity.

A good quality meeting that was well worth attending.

Indexing (with derived space group and lattice symmetry determinations) is considered a prelude to determining the crystal structure, and permits phase identification by lattice matching techniques. The Rietveld method is used to refine crystal structures and is perhaps best considered whole- pattern-fitting structure refinement, i.e., we must account not only for the crystal structure but also the instrumental resolution and diffraction physics effects (e.g., crystallite size and strain). The aim is to perform quantitative phase analysis and identification.

This workshop introduces the theory and formalisms of various indexing methods and structural refinement techniques. One unique aspect of this workshop is the extensive use of computer laboratory problem solving and exercises that teach method development in a hands-on environment. We will use EXPGUI and GSAS for the Rietveld laboratory work; Crysfire (especially Dicvol, Ito and Treor) will be used for indexing exercises.

Take the three-day basic workshop, the three-day advanced workshop or attend the full week of hands-on training.  Please refer to the pre-requisites below if interested in attending only the Advanced Rietveld workshop:

Pre-requisites for Advanced (II):

  • You have previously attended the ICDD Basic Rietveld workshop.
  • You use Rietveld refinement on a daily basis.
  • You have a basic understanding of crystallography.
  • Please contact an ICDD Rietveld faculty member: John FaberJim Kaduk, or Tom Blanton, for approval to attend only the advanced workshop.

The format of the workshop is a combination of morning lectures and afternoon computer lab exercises. Ample opportunity for individual student-faculty interaction exists throughout the week.

Tuition Waiver Opportunities

ICDD offers a limited number of tuition waivers for the Rietveld Refinement & Indexing workshop. Faculty members and graduate students are encouraged to apply. If you are currently developing a program in Rietveld Analysis, and are interested in incorporating these topics into an established course, a tuition waiver can provide you with the opportunity to learn the principles and practices from some of the experts in the field.

Transfer, Cancellation and Refund Policy

ICDD must guarantee payment for meals and materials in advance.  You will receive a 50% refund of the paid registration fee if your written cancellation is received at ICDD 20 business days prior to the start of the class.  With less notice, a colleague may take your place, or the course materials will be mailed to you, but no refund will be given.

Please note: A minimum of 10 registrants per course is required, otherwise the course will be cancelled and your registration fee will be refunded. You will be notified of a course cancellation no later than two weeks prior to the start of the course.

If you have any questions, please contact Eileen Jennings, Education Coordinator at clinics@icdd.com
