I03 – Macromolecular Crystallography
Overview
I03 is a highly automated beamline for macromolecular crystallography, supporting rapid data collection from protein crystals at cryogenic temperatures. It is optimised for high-throughput screening and for challenging targets such as membrane proteins.

Data collection
Diffraction from a crystal lattice obeys Bragg's law [math]n\lambda = 2d\sin\theta[/math], where [math]d[/math] is the lattice spacing. The accessible resolution depends on the X-ray wavelength and detector distance.
| Parameter | Value (demo) |
|---|---|
| Energy range | 5–25 keV |
| Beam size | Variable, micro-focus available |
| Detector | Hybrid pixel array |
Safety induction for visiting users
All visiting users must complete the online safety induction before arriving at Diamond. The induction covers radiation safety, the experimental hall rules and what to do in an emergency.
- Complete the induction in the User Administration System (UAS) at least 48 hours before your visit.
- Bring photo ID; your site pass is issued at reception.
- Read the experimental hall safety rules and your beamline's local rules.
Accessing your data after your visit
Data collected at Diamond is stored centrally and can be accessed remotely after your visit using your FedID. Raw data is retained in line with the Scientific Data Policy.
Automated processing pipelines run during your experiment; results appear alongside raw data within minutes.
