Real‐time XFEL data analysis at SLAC and NERSC: A trial run of nascent exascale experimental data analysis [PDF]
Concurrency and Computation, 2021 X‐ray scattering experiments using free electron lasers (XFELs) are a powerful tool to determine the molecular structure and function of unknown samples (such as COVID‐19 viral proteins). XFEL experiments are a challenge to computing in two ways: (i) due

Online dynamic flat-field correction for MHz microscopy data at European XFEL
Journal of Synchrotron Radiation, 2023 The high pulse intensity and repetition rate of the European X-ray Free-Electron Laser (EuXFEL) provide superior temporal resolution compared with other X-ray sources. In combination with MHz X-ray microscopy techniques, it offers a unique opportunity to

Preliminary XFEL data from spontaneously grown endo-1,4-β-xylanase crystals from Hypocrea virens.
Acta Crystallographica Section F Structural Biology Communications, 2022 The enzymatic degradation of semi-cellulosic substrates has recently received immense attention. The enzyme endo-1,4-β-xylanase is essential for the complete digestion of complex and heterogeneous hemicellulose.

Terawatt-scale sub-10-fs laser technology - key to generation of GW-level attosecond pulses in X-ray free electron laser [PDF]
, 2004 We propose a technique for the production of attosecond X-ray pulses which is based on the use of X-ray SASE FEL combined with a femtosecond laser system. A few-cycle optical pulse from a Ti:sapphire laser interacts with the electron beam in a two-period

Multiple-core-hole resonance spectroscopy with ultraintense X-ray pulses
Nature Communications, 2023 Understanding the interaction of intense, femtosecond X-ray pulses with heavy atoms is crucial for gaining insights into the structure and dynamics of matter. One key aspect of nonlinear light–matter interaction was, so far, not studied systematically at

The MiniSDD-Based 1-Mpixel Camera of the DSSC Project for the European XFEL
IEEE Transactions on Nuclear Science, 2021 The first DSSC 1-Mpixel camera became available at the European XFEL (EuXFEL) in the Hamburg area in February 2019. It was successfully tested, installed, and commissioned at the Spectroscopy and Coherent Scattering Instrument.
