Due to the fire incident in the Deuteration Facility Synthetic Lab, in May 2021, the D-laboratory is currently working at reduced capability, and requests for D-materials are limited to either stock materials or materials with less complex synthetic procedures during this round.  If you do have a need for D-materials for a proposed experiment please contact the D-lab team (​) to discuss the request before submitting your proposal - we will do our best to meet your deuteration requirements.

ISIS has returned to pre-Covid ways of running experiments after the long shutdown.  This means that we will expect an experiment team to come to ISIS to run their experiment.  Please ensure you have an experiment team able to come physically to ISIS before submitting a proposal.

​ISIS neutron and muon instruments are free at the point of access for academic and industry researchers, provided the results from experiments are published in the public domain.  Terms and conditions for accessing ISIS can be found here and useful information to note before applying can be found here​.

New users are always welcome at ISIS Neutron and Muon Source and we are constantl​y encouraging new areas of research that can flourish.  There are a number of routes for acad​emics and industry​ to access beamtime.  Please ​browse the box links below for further important information and guidance including links to our instrument pages​​​.
