HomeApply for Beamtime

There will be no proposal round in April 2014 due to the long shutdown

Next call will be in Autumn 2014 for beamtime in 2015

ISIS neutron and muon instruments are free to use for academic and industry researchers, provided results from experiments at ISIS are published in the public domain.

New users are always welcome at ISIS and we are constantly encouraging new areas of research that can flourish. ISIS scientists and the User Office can help you with your beam time proposal, and all ISIS users receive a high level of support during experiments.

For Academics

Types of beamtime

We offer a range of ways to request beam time on ISIS instruments: Direct access, Rapid access, Xpress access, Commercial Access and Programme access.

EU funding for experiments at ISIS

ISIS has a limited amount of funding available each round to support experiments for researchers from EU countries.

Xpress Service

Gem Xpress

Powder diffraction measure-by-courier service using the Gem instrument


MERLIN Xpress is the new inelastic neutron scattering measurement-by-courier service for powder samples, using the high count-rate MERLIN spectrometer.

Muon Xpress

Muon spectroscopy measure-by-courier service using the Emu and MuSR instruments

QENS Xpress

Quasi-elastic neutron scattering measure-by-courier service using the Iris and Osiris instruments

SANS Xpress

Small-angle scattering measure-by-courier service using the Loq and Sans2d instruments. Please note: because of the ISIS maintenance shutdown beginning in August 2014 we are unable to accept any more SANS Xpress proposals until next year.

Tosca Xpress

Molecular spectroscopy measure-by-courier service using the Tosca instrument


Spin-echo small-angle scattering measure-by-courier service using the Offspec instrument

For Industry

ISIS Collaborative R&D Programme

The ISIS Collaborative R&D programme is a fast-track route for industries with a UK manufacturing or research base to use ISIS neutron and muon beams.

Notes and guidance

Writing a beam time proposal for ISIS

Beam time allocations at ISIS are highly prized and in great demand. A clearly written proposal for an experiment at ISIS can set you apart from the crowd and greatly increase the chances that the Facility Access Panels will recommend you get allocated beam time. We give you hints and tips on writing the perfect proposal.

Responsibilities of the Principal Investigator on ISIS proposals

The Principal Investigator on an ISIS proposal has specific responsibilities for the experiment.

Publishing research

Guidence for publications.

Experimental Reports

An experimental report must be completed for each experiment made at ISIS once it has been completed.


Consumables for ISIS experiments

Oxford Isotope Facility
