Guidelines for writing a good proposal science case can be found here. Proposal review panel members strongly encourage the use of the template and adherence to the formatting instructions.

To submit a proposal visit the ISIS Online Proposal System

Please speak to a relevant instrument scientist before submitting your proposal.

Documentation on using the submission system can be found here: https://www.isis.stfc.ac.uk/Pages/Proposal-System.aspx

If deuterated materials are required, it is strongly advised that you contact the ISIS Deuteration Facility (ISISDeuterationFacility@stfc.ac.uk) before submission to discuss feasibility.

An experimental team must come to ISIS to perform the experiment. Please ensure you have an experiment team able to come physically to ISIS before submitting a proposal.

We acknowledge that submission system performance issues were experienced during the last call for access. These issues have been identified and resolved to ensure a smoother and more reliable submission experience during this call for access.

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.

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