Faster grid scans are now available in beta mode. Data collection is at approx the max frame rate of the detector. Please ask your local contact if you would like to try them out.
Please note this form of grid scan is very much in a testing phase during this run (Nov/Dec 2018) so it might not always work prefectly. If you do run into problems, switching modes is relatively straightforward. Please provide feedback!
Over the last couple of years we have been developing serial data collection (SSX) based on fixed targets. We are now at a point where we can offer fixed target (and other modes of) SSX to interested users during the final stages of commissioning.
For a very brief overview see the I24 serial webpage. If you have any questions please get in touch.
Grid scans have now been sped up by almost an order of magnitude using an approach developed from the one we use for fixed target serial crystallography Sherrell et al. J. Synch Rad (2015), Owen et al. Acta Cryst D (2017).
The grid shown to the right now takes ~40s compared to ~300s previously thanks to an optimised path being taken and a new mode of motion control. We expect further speed ups in the near future as we further develop the approach.
You can now queue hits from grid scans for data collection. For further information on this brief instructions see the grid scan page.
Fast grids are available on both goniometers.
Data from multiple crystals/wedges can be automatically processed together using multi xia2 or xia2.multiplex. For a brief overview see the multi crystal data processing page.
(RT and cryo)
Kappa available for simple reorientation of samples.
The kappa is not always mounted by default. It is available for use - just email your local contact in advance of your beamtime.
Please email a week in advance: this will allow us to mount and test on the preceeding machine day.
(in situ )
In situ available.
The change between 'normal' and in situ modes takes less than 2 minutes and is fully automated. Currently trays must be mounted manually.
|Grid scans||Operational||Fast grids with queued data collections based on hits now available. Further information here.|
|Line (helical) scans||Partly operational||Ongoing fault with helical/continuous line scans in GDA. Wedged line scan works fine|

|Remote data collection||Operational|| |
Please consider coming to the beamline for data collection, especially for day shifts and/or if you have a challenging project. There is a lot of new equipment and we are more than happy to spend time explaining how it works and how you can best exploit it for your experiment.
|Serial data collection||Beta mode||Fixed target and LCP extruder experiments available on a collaborative basis. An overview can be found here. Please contact the PBS for further information.|
