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. Fully confidential fast-tracked use of the instruments is also available for industrial and commercial customers. If you are ready to put forward a proposal visit the ISIS Online Proposal System or, to submit an industrial proposal, contact Dr Christopher Frost.
There are a range of ways to access beamtime: Direct access, Rapid access, Xpress access and Industrial access. A short guide to ISIS beamtime access routes is available and more detail can be found on our beamtime access routes page. It is also possible to submit a proposal for an experiment that involves beamtime at both ISIS and Diamond, and you can find more information on our joint proposal page.
Key Dates and ISIS long shutdown
A diagram of the currently-planned proposal rounds and run cycles is shown below.
ISIS will have a long shutdown to enable refurbishment of the first target station and replacement of a tank in the linear accelerator. Delays to these projects as a result of the Covid-19 situation mean that we have moved the long shutdown dates so that it will start on 21 June 2021.
The next ISIS run cycle will begin in April 2021. Time in this run cycle was allocated in the Dec 2019 Facility Access Panel meetings.
The next call for proposals is therefore likely to be towards the end of 2021 (for TS2 only) – further details will be given in due course.
Instruments and contacts
Before submitting a proposal, visit our instrument pages to determine which is most suitable for your work, and discuss your proposal with the relevant instrument scientist. This is a requirement for Rapid access and Xpress proposals, but ISIS scientists are always willing to review proposals before submission.
Beamtime allocations are highly prized and in great demand. Discover hints and tips on writing the perfect proposal and proposal templates in our proposal writing guide.
ISIS operates seven Facility Access Panels (FAPs) to peer review all beamtime proposals. More information about the panels can be found on our FAP page.
ISIS provides support with equipment, general procedures and supplementary techniques related to the preparation of samples for experiments. This includes access to our Support Laboratories, Sample Environment teams and the Research Complex at Harwell.
There are a number of terms and conditions of access to the ISIS facilties, including data management and privacy.
