Powder X-ray diffractometers (XRD) are omnipresent at labs around the world. They are commercially available and typically produce a lot of very good data. Unfortunately, much of the data is not exploited to its full extent. In part, this is due to the fact that scientists use XRD as one of many experimental methods, but another important reason is that the analysis of the data seems cumbersome to many XRD users. The available software offers so many options that a first-time user easily gets lost.
With this hands-on workshop+school on Powder Diffraction we intend to help participants to overcome the barriers to look into their data in greater detail. In a 2-day intensive course the participant will learn the basic theory behind powder diffraction and how crystallographic analysis of their (own) data helps them to answer concrete questions on the material of their subject.
We invite PhD’s and postdocs to apply for this course. We encourage participants to send a description of their science case and how they would like to use diffraction and crystallography to answer the related questions. XRD and neutron powder diffraction (ND) facilities are available to measure their own sample during the course and the obtained data can be analyzed under supervision of powder diffraction experts.
The fee for participants is 125 euro for academia and 500 euro for non-academia. The fee includes lunch, tea/coffee and the dinner, but does not include accommodation.
