A pipeline for megahertz X‐ray photon correlation spectroscopy on soft matter samples at the MID instrument of European XFEL

Journal of Synchrotron Radiation, EarlyView.
We present a standardized and highly automated pipeline for megahertz X‐ray photon correlation spectroscopy (MHz‐XPCS) on soft‐matter samples at the MID instrument of the European XFEL. The workflow addresses AGIPD petabyte‐scale data handling, detector‐artifact correction, correlation analysis and FAIR data output, enabling routine MHz‐XPCS with ...

Fast‐scanning small‐angle X‐ray scattering of hydrated biological cells

Journal of Synchrotron Radiation, EarlyView.
Fast‐scanning small‐angle X‐ray scattering on biological cells in aqueous environments reveals intracellular anisotropy and orientation, and allows for systematic assessment of radiation damage caused by the measurements.Due to their high penetration depth, X‐rays enable us to obtain information from the interior of whole unsliced cells. Scanning small‐

Neural Networks for Handwritten English Alphabet Recognition

, 2012
This paper demonstrates the use of neural networks for developing a system that can recognize hand-written English alphabets. In this system, each English alphabet is represented by binary values that are used as input to a simple feature extraction ...

Imaging gas in a combustion engine with high‐energy X‐ray Compton scattering

Journal of Synchrotron Radiation, EarlyView.
Compton‐scattering imaging has been applied to a combustion engine under operation for the first time. With a time‐resolved technique, a crank‐angle dependency of Compton‐scattered X‐ray intensity is obtained at different positions in a combustion chamber.We have developed a time‐resolved Compton‐scattering imaging technique for visualizing gas ...

A robotic goniometer exchanger for high‐throughput single‐crystal X‐ray diffraction at SPring‐8

Journal of Synchrotron Radiation, EarlyView.
A compact six‐axis robotic arm has been implemented at the BL02B1 beamline of SPring‐8 as a high‐precision goniometer for single‐crystal diffraction. Its programmable control enables automated sample handling and centring, advancing autonomous high‐throughput diffraction in preparation for SPring‐8‐II.Rapid and reliable sample handling is essential for

Time‐resolved XPCS analysis across broad time‐scales using multi‐tau two‐time correlations

Journal of Synchrotron Radiation, EarlyView.
A scalable multi‐tau two‐time correlation framework enables efficient, time‐resolved XPCS analysis of long duration high‐frame‐rate modern synchrotron data while preserving sensitivity to non‐stationary dynamics.We present a multi‐tau two‐time correlation (MT‐2TC) analysis for X‐ray photon correlation spectroscopy that enables efficient analysis of ...

Development of electron source feedback for enhanced X‐ray beam stability at NSLS‐II

Journal of Synchrotron Radiation, EarlyView.
An electron‐source feedback method has been demonstrated at the NSLS‐II Hard X‐ray Nanoprobe, using X‐ray beam position data to drive electron beam corrections. The approach suppresses dominant vibration peaks and significantly improves X‐ray beam stability and ptychographic image quality.Future synchrotron light sources are being designed to deliver ...

A new reference for changes in X‐ray scattering from water due to temperature changes at ambient conditions

Journal of Synchrotron Radiation, EarlyView.
A newly measured reference dataset for the temperature differential scattering signal of water, acquired at the DanMAX beamline of the MAX IV synchrotron, is presented.The X‐ray solution scattering from water S(Q)H2O depends on temperature and density, a phenomenon that is utilized in, for example, temperature‐resolved and ultrafast time‐resolved X‐ray
