High data rates produced by custom-built burst mode detectors available at the European XFEL present challenges for data processing. One crucial processing step required for subsequent analysis is detector calibration and data correction. We present an overview of the calibration and correction software infrastructure developed at the European XFEL to accommodate the specific needs at the facility. We discuss the distinction between offline and online processing, outlining the roles and interesting technical properties of calibration software in both contexts. Recent improvements to the online processing software allow for correcting full detector data stream in near real time, enabling more comprehensive online analysis methods for improved steering of experiments.
Fundamental electron dynamics at the attosecond frontier and their direct coupling to structural dynamics of matter yield novel insights into the energy-distribution and protection mechanisms of Nature. The angular-streaking technique has exclusively demonstrated its capability of obtaining the full time-energy structure of XFEL pulses with attosecond resolution directly in the time-domain, thus enabling XFELs to study electron dynamics from element-specific vistas and their importance as onset of subsequent structural dynamics. We will present latest advances of this technique together with first results from the 2022 EuXFEL atto-campaign and the complementary prospects of the FLASH 2020+ innovation project at DESY.
