Under Pressure: Exploring Matter at or under Extreme Conditions at Diamond

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.
