This session for new & less experienced European XFEL users is a brief summary of the systems & infrastructure which you'll use to work with data produced at a beamtime. We'll talk about how to prepare for data collection, and show some of the tools you might be using to analyse data during & after your experiment.
This talk will cover new developments from the Data department in addition to highlighting notable achievements in 2025. The past year saw many new additions to our data analysis software suite, EXtra. There is now a new GUI interface (extra.gui) which features a graphical tool to calibrate 2D spectrometers in Jupyter and a couple of widgets for ROI and peak selection. Another big addition...
The new Scientific Data Policy takes effect for all user proposals starting in 2026, which includes the introduction of data management plans and data reduction as an integral part of the proposal lifecycle. Over the past two years, the necessary workflows have been developed as part of pilot programs in conjunction with users of select experiments.
Here we present a practical end-to-end...
Charge transfer is essential to many complex chemical processes and thus a thorough understanding at the molecular level is desired. One particular aspect concerns the interplay between the positions of nuclei and the probability of charge transfer. During a beamtime at EuXFEL's SQS instrument, we studied how the ability to transfer electrons in dissociating molecules with a rotating fragment...
I will introduce Time resolved X-ray solutions scattering as a technique and outline some of the challenges associated with measuring at ~100 kHz X-ray repetition rate.
I will discuss the data pipeline that we have developed in conjunction with the data analysis group and outline how that helped solve these challenges.
High rep-rate data requires high rep-rate solutions, where human-in-the-loop decision making no longer sufficient to manage many experiments efficiently. Simultaneously, the requirement for high-level, (near-) online analysis to manage experiments is often explicitly at odds with their goal: to do something new where you don't know exactly what you'll see. I'll walk through how HED have built...
Research done at European XFEL takes advantage of both high-throughput data, as well as the enhanced data quality. Different research topics are being explored to ensure that we continue to deliver increasingly high-quality data. The presentation expands on selected projects and research topics within three main areas. One topic includes beam automation and instrument alignment automation,...
