Abstract

Following the ESRF upgrade and the reconstruction of the storage ring in 2019, the increased brilliance allows new experiments to be carried out, with improved precision and pushing further the detection limits of subtle structural changes occurring in the materials. High-angular resolution powder diffraction, with well-defined and resolved diffraction peaks, is used generally to obtain high-quality data for complex structure refinements. The ID22 beamline of the ESRF is equipped with a Dectris Eiger2 X 2M-W CdTe pixel detector receiving the X-rays transmitted by the thirteen crystals of a custom-made multi-analyser stage [1]. A great advantage of this arrangement is the axial resolution provided by the 2D detector, which allows the effect of axial divergence, which causes the low-angle asymmetry in the peak shape of powder diffraction patterns, to be removed. A second advantage is that the axial acceptance of the detector can be increased as 2𝜃 increases, up to the 38 mm width of the detector, thus increasing the statistical quality of the high angle data while also improving the angular resolution. ID22 has implemented this approach systematically, as an automatic procedure, into its collection of high-resolution powder diffraction data. A case study developed inhouse in relation to the trapping of CO2 in microporous materials will be presented [2], benefitting from the overall improvement of the high-resolution data quality.

About the ECA Lunch webinars:

The ECA lunch webinars with an educational or scientific focus were invented following the strong wish to strengthen and vitalize the European crystallographic community. They are a monthly webinar series by the European Crystallographic Association (ECA) and involve all GIGs/SIGs.

The webinars are organized in an online setting such as Zoom (45min + 15min Q&A) and take place every first or second (depending on the schedule of other ECA activities) Thursday of a month at lunchtime (1:00 PM CET). Webinars will be announced via social media, mailing list, and here.

The webinars are organized by a steering committee of GIG01-members:
Breternitz, Joachim
Gaidamaka, Anna
Germann, Luzia
Hans, Philipp
Mazzeo, Paolo P.
Morana, Marta
Pisacic, Mateja
Prencipe, Michele
 

 

 
Advisory board:
Heinemann, Udo
van der Lee, Arie

 

The ECA Lunchtime Webinars are on a break over the summer and will restart again soon!
