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 access call page for more informationUser with notepad

To submit an industrial proposal, contact Dr Christopher Frost. ​ 

Access Routes

There are a range of ways to access beamtime: Direct access, Rapid access, Xpress access and Industrial access.​ A short guide to ISIS be​amti​me 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
