Beamline I15 is dedicated to X-ray powder diffraction experiments at extreme pressures and temperatures. Research topics include fundamental Physics and Chemistry, Earth and Planetary Science as well as Materials Science and Engineering.
The beamline provides monochromatic high-energy X-rays from 20 to 80 keV. These X-rays focussed and collimated down to ≤20 µm can penetrate into complex sample assemblies permitting detailed mapping of structural order or disorder, chemical fingerprinting or structure determination.

Following the second compressor failure in August, four new compressors were ordered so that all of them could be replaced, and leave a spare. These arrived in Oct and means that we have effectively completely replaced the He cooling system with new compressors and refurbished coolers on the superconducting magnet. However the company has now told us that one of the refurbished cold heads has failed, and even though we ordered spare parts for these back in August they cannot deliver until late November. We have pursued every option possible at this time, but the company are unable fix it in time for the run starting next week. We are thus having to cancel all beamtime during Nov and Dec. Beamtime scheduled for Jan through March will remain scheduled assuming the latest repairs planned in Dec are completed with no further issues. We are deeply disappointed that these problems have not been resolved despite vigorous and continuous engagement with the company. We are continuing to strive to fix the situation as soon as possible and are reconsidering our long-term options.
We have changed our DAC policy and split it into DAC loaning only and DAC loaning + sample loading. Please familiarize yourself with the details under the DAC Policy tab here.

I15 has acquired a micromanipulator 'Axis Pro' from MicroSupport Co. It is now available to users. Watch this video from MicroSupport to see the loading of a diamond-anvil cell with the Axis Pro. It is amazing!!
