TOPAS School

“Structure Determination and Refinement”

Bruker is pleased to announce a TOPAS School with hands-on training to be held from 17-19 May 2023, at ICDD Headquarters, Newtown Square, Pennsylvania.

The primary topic of the school is to teach participants the operation of TOPAS for structure determination and refinement from powder diffraction data. Participants should be familiar with the basics of crystal structure analysis. Previous knowledge of TOPAS is not required but is an advantage.

Training contents:

  • Indexing using the Least-Squares Indexing (LSI) method
  • Pawley and Le Bail refinements
  • Ab-initio structure determination using Global Optimization
  • Structure refinement using the Rietveld and Two-Stage methods
  • Use of (laboratory and synchrotron) X-ray data and neutron data
  • Introduction to pair distribution function (PDF) analysis

Note: Bring your up-to-date laptop to perform exercises in the hands-on sessions. You must have Win10 (64bit) or Win11 (64bit) installed, administrator rights, and functioning WLAN and USB ports. TOPAS V7 and temporary licenses will be made available onsite. If you don’t want to bring a laptop, or if your laptop does not fulfill the requirements, you may follow the exercises on the main screen.
