Training
Meet and Greet
Our staff will be attending the following meetings and would be pleased to connect with you. Feel free to stop by for a conversation or to discuss any questions you may have.

Jungfrau at I24
As part of a series of ongoing upgrades, beamline I24 has been successful in securing BBSRC funding for a new integrating Jungfrau 9M detector supplied by the Paul Scherrer Institut. The Jungfrau detector will replace I24’s Pilatus3 6M which has served users for a good number of years. The CdTe Eiger2 9M detector will be the work-horse detector while the Jungfrau is in a commissioning phase for both rotation and serial data collection.

Diamond MX provides a comprehensive suite of data and downstream processing pipelines, including experimental phasing. All results are accessible via SyncWeb.
To enable downstream processing pipelines, it is highly recommended to include the following when preparing your samples at shipment and they must be in place prior to data collection:
If a protein sequence is provided, an AlphaFold model will be generated to support molecular replacement (MR) in addition to any PDB that user have supplied.
⚠️ Important: When viewing data reduction results, please be aware of alerts and warnings that appear immediately upon selection to get an overview of various suggested crystal pathologies in your dataset.
For datasets collected across multiple wedges, orientations, or regions of a crystal — or if trimming is required — data reprocessing tools available on SyncWeb can be used to refine your results.
If you have any questions or feedback regarding the data processing, please feel free to reach out to us.
1. Interesting paper on multi-crystal approach using intensities-based clustering
Thompson, A. J., Beilsten-Edmands, J., Tam, C., Sanchez-Weatherby, J., Sandy, J., Mikolajek, H., Axford, D., Jaho, S., Hough, M. A. & Winter, G. (2025). Enhanced intensity-based clustering of isomorphous multi-crystal data sets in the presence of subtle variations. Acta Cryst. D81, 278-290.
2. In case if you have missed it, paper from our sub-micron focus beamline (VMXm) is out in JSR
Warren, A. J., Trincao, J., Crawshaw, A. D., Beale, E. V., Duller, G., Stallwood, A., Lunnon, M., Littlewood, R., Prescott, A., Foster, A., Smith, N., Rehm, G., Gayadeen, S., Bloomer, C., Alianelli, L., Laundy, D., Sutter, J., Cahill, L. & Evans, G. (2024).VMXm – A sub-micron focus macromolecular crystallography beamline at Diamond Light Source. J. Synchrotron Rad. 31, 1593-1608.

X-ray crystallography is a powerful technique used to determine the 3D structures of biological macromolecules, which plays a crucial role in understanding their functions and interactions. The quality of the data collected from X-ray diffraction experiments is critical for the success of structure determination and subsequent analyses.
With advancements in technologies, such as brighter synchrotron sources and more sensitive detectors, the limitation in X-ray diffraction data collection has shifted from the capabilities of the instruments to the radiation damage of the sample.
