In experiments conducted at 4th-generation synchrotron radiation and free electron laser (FEL) beamlines, the primary challenge for X-ray optical elements is to achieve and maintain focused X-ray beams with high intensity, near-perfect wavefront quality, and exceptional stability. Additionally, in diffraction-limited light sources that produce coherent photons, preserving well-controlled...
The historical limitations with data collection at synchrotron facilities have been, by and large, solved. Today, imaging beamlines can acquire 100s of tomograms per hour at a sustained rate. Similarly, high-quality 3D reconstruction of the 2D raw data is now completed within a few minutes of the last radiograph hitting the disk. Resultingly, users leave a typical tomography beamtime session...
We have implemented a system for fully real-time processing of data from serial X-ray protein crystallography experiments. The system handles the full data rate from a 16 megapixel Dectris EIGER2 X detector at 133 frames per second, performing the standard serial crystallography data processing pipeline consisting of peak search, diffraction pattern indexing, spot “prediction” and...
Increasing brightness of new generation light sources and developments in X-ray detectors allow faster experiments and higher data rates. Reducing data first before storing them is one of the most effective strategies of dealing with expanding data volumes. The effective and real time data reduction is also imperative to near-real time experiment feedback, dynamical events selection and data...
The control system used at the Taiwan Photon Source TPS31A PXM endstation is composed of an integrated system capable of achieving fully automated sample scanning and data retrieval. This system consists of six main subsystems (Figure 1):
(a) Central Control System: Integrated by a computer system, allowing remote control.
(b) Sample Alignment System: Used to measure and extract the scanning...
Advancements in synchrotron and X-ray free-electron sources and associated developments in instrumentation and techniques offer many new possibilities for researchers. At the same time there is increasing demand and pressure to make measured data accessible to the wider community through improved research data- and metadata- management, and for implementation of FAIR data principles by which...
The European XFEL is a megahertz repetition-rate facility producing extremely bright and coherent pulses of duration of the order of few femtoseconds or less. Owing to its X-ray imagers, specifically built to operate at these repetition rates (AGIPD, DSSC and LPD), the amount of data generated in the context of user experiments can exceed hundreds of gigabits per second, resulting in tens of...
