News and Current Status

A Jungfrau 9M detector has arrived at I24 and excellent quality data already collected. For further information see the JF9M page. If you are interested in using the JF9M please contact beamline staff.

The CdTe Eiger2 9M is the work-horse detector at I24 it is optimised for high energy data collection (>17keV) and has been shown to give better diffraction for a given X ray dose into your sample. Particularly beneficial for small crystals. 

For more info on see the eiger page here

The current accessible energy range is 7.9 -24 keV.

The high energy range will be extended as commissoning continues. If lower energies are a priority for you please let us know in advance of your beamtime: the eiger will work well but the resolution you can collect to may be limited due to the area of the detector

The beamline flux is shown in the image below. If you need a number ask your local contact. If you need an accurate flux please ask your local contact in advance of your beamtime.

UV-Vis data collection is available. While data collection works well, there are some constraints as the setup is currently incompatible with the sample changer. Please contact beamline staff to discuss.

Serial data collection is routine. Our primary offering is fixed target SSX and we can also offer extruder-based data collection. Though other approaches are possible and we are always happy to discuss new ways of collecting data.

Dynamic SSX is possible using LEDs, the PORTO laser system or drop-on-chip.

For a very brief overview see the I24 serial webpage.  Send us an email if you are interested in a serial experiment - we are happy to help with experiments from very first screening of crystals through to more complex time-resolved sessions using a laser or a drop-on-chip approach.

Multiplex is a powerful tool to optimally merge wedges of data together. It can be run automatically or manually.

For a brief overview of how to run in manually see the multiplex news page.

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.
