O 62: Focus Session: Big Data in Aquisition in ARPES (joint session O/CPP)
Mittwoch, 18. März 2020, 10:30–13:15, REC C 213
Due to the advancement of both electron detectors and light sources, ARPES data is increasing in volume and complexity. This applies to ARPES performed at 3rd and 4th generation light sources as well as lab-based sources. We have reached a point where data handling, workflow management, visualization and analysis is a severe challenge and potentially become the bottleneck in our workflows rather than data acquisition itself. Currently there exist mainly isolated, i.e. lab- or facility-specific, solutions for data acquisition and file formats, metadata definitions, data-processing workflows, and analysis approaches. A community-wide ARPES (meta)data schema in the quest for reproducible, scalable and transparent data analysis is not yet established. This focus session aims to reveal the great potential for speeding up our progress by attacking certain challenges in joint efforts.
