Example Diffraction Datasets for Beamstop Alignment QC

This archive contains example X-ray diffraction datasets collected on the I04 beamline at Diamond Light Source. These datasets are intended to serve as test cases for the data analysis tools in the mx_beamline_setup project (https://github.com/aragaod/mx_beamline_setup), specifically for scripts that analyse beamstop alignment and overall data quality. The data consists of several collections taken with the detector and beamstop positioned for different resolution ranges (e.g., a 'high-resolution' setup and a 'low-resolution' setup). Collection Date@ 26th February 2025Facility: Beamline I04, Diamond Light Source, UK Common Data Collection Parameters Detector: Eiger 16MFlux: 1.12e+12 ph/sOmega Start: 0.0°Omega Oscillation:0.20°Number of Images: 1Wavelength: 0.9537 Å (13,000 eV)Exposure Time: 0.2000 sDose: 0.10 MGyTransmission: 100.00%Beamsize: 32x20 μm Data Format The data is stored in the NeXus/HDF5 format. Each dataset is split into three files: A _master.h5 file containing the primary metadata and links to the other files. A _meta.h5 file containing detector-specific metadata like masks and flatfields. A _..._000001.h5 data file containing the raw pixel values for the diffraction image. To analyse a dataset, you should always point the analysis software to the corresponding _master.h5 file.
