​ISIS has returned to pre-Covid ways of running experiments after the long shutdown.  This means that we ​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.​

The ISIS Policy on the use of AI in proposal and science case writing can be found here,​​ and must be adhered to if AI is used at any point of the proposal writing process.​​

​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​.  If experimental time on multiple instruments is required, please submit a separate proposal application for each.  ​We are not able to provide T&S costs for users travelling from outside the UK​.​  For users funded through our EU Access grant or through an overseas ISIS-partnership agreement or access route, we will reimburse your travel expenses but you should make your own travel arrangements.​​
