13th July 2020: i24 is open for standard remote access experiments. Please read the guidelines carefully. In case of questions, or for information about more complex experiments such as SSX, please contact the beamline staff.
Please see the News and Current Status tab for the latest updates
A new detector - the CdTe Eiger2 9M - is here! - see News
Fast grid scan and queuing based on grid scan results now available - see News
I24 is a tuneable microfocus beamline for MX. It was the first beamline if its kind to be built in Europe and has been operating since 2008. In 2015/2016 the beamline was completely rebuilt with a new dual goniometer endstation and new mirrors.
The beamline offers extremely high flux densities with the ability to investigate virus structure, membrane proteins, microcrystals (crystals as small as 1.5 microns have been measured successfully). It combines versatile optics and the most sophisticated detectors available with the most advanced automation systems to enable sample location, data collection and analysis.
We offer two standard modes of data collection: cryo (SPINE pins) and in situ. We also offer serial (fixed target, thin film and LCP extruder) data collection. Serial data collection is in a developmental stage and any early experiments can only be done in collaboration with beamline staff - if you're interested please contact the I24 PBS. We are always happy to try new or challenging experiments: get in touch if you have a experiment we can help with.
Please email us details of any problems you run into, or any other comments or suggestions.
Data processing - vertical goniometer
Please remember to take the vertical rotation axis into account when processing your (pin) data.
In XDS use ROTATION_AXIS= 0 -1 0
Ask your local contact if you need a hand, or if you have any questions.

Please discuss your requirements with your local contact or a member of the beamline team before your experiment especially if you want to do something out of the ordinary. We are always happy to try and do novel or difficult experiments - get in touch if you have an ambitous idea...
Shift timings: unless explicitly arranged with beamline staff, the start and end times of all (academic, industrial and in-house) shifts are as below:
|
Time |
Shift |
| 9am-10am | Beamline Startup |
| 10am-5pm | Day Shift |
| 5pm-1am | Evening Shift |
| 1am-9am | Night Shift |
Please note:
In both cases you will emailed details of when the shift starts/ends. In case of questions get in touch with your local contact.
