MassDiff: Development of post-processing tools for time-resolved data
Coordinating university or institute
Facility
DESYProject description
The project started with Vinnova funding based on industrial needs to analyze existing time-resolved diffraction experiments and continued with internal resources from Swerim.
Within the project, a program tool was developed for visualization and fitting of diffraction peaks. The tool can be used to convert data type, visualize, and inspect many data sets and perform quantitative analysis after performing peak fitting operations. The program enables single and multi-peak fitting using the internal engine, and LeBail/Pawly/Rietveld analysis by using Topas or Topas-Academic (and currently being developed for MAUD). The standalone version of the program is user-friendly and does not require any programming skills. For experienced users who need new functionalities or modification, the source code is also available.
The program tool has continued to be developed and tested within several diffraction projects e.g. Vinnova-funded projects for data collected at different photon and neutron facilities as well as laboratory-based diffraction data.
