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.
The provision of I15 diamond-anvil cells (DACs) and/or sample loading for user experiments as a general service that can be requested has ceased.
Users who are interested in using I15's DACs for experiments please contact I15 staff to discuss a collaboration. Please do this well before a proposal submission deadline to ensure staff have time to discuss the proposed collaboration.
Similarly, users who are interested in using I15’s gas loading system for experiments please contact I15 staff.
The equipment is offered on a collaborative basis for academic users; industrial users should contact the Industrial Liaison Office.
The Rapid Access Route now is available for
• data collections on samples that are timely and of high scientific interest.
• measurements that will be included in a publication as a reply to referees’ comments.
• a pilot or proof-of-concept study to evaluate feasibility before submitting a future full proposal.

We are delighted to share with you that the upgrade of the cryocoolers of the I15 wiggler by the Diamond Insertion Device Group has been successful. I15 & I15-1 received beam into their experimental hutches on the 24th of January. The upgrade ensures a more robust and continuous operation for the beamlines. In order to de-risk future operations even further, Diamond Management have now sent out a call for tender for companies to offer to supply a new wiggler, which would be a spare or replacement for I12 or I15.
I15 resumed its user programme on the 27th January. All I15 users with allocated beamtime have been scheduled to receive their time before October 2023.
