Applying for beamtime

User Club

The ILL User Club provides online access to all the information and administrative tools for our scientific visitors, presented in a user friendly environment.

Other types of access

There are other ways of submitting a proposal to the ILL :

  • Submission of a TEST form 
  • Submission of a CRG proposal (CRG)
  • Special access for industrial users (INDU)
  • Submission of a D-Lab proposal (DEUT)

TEST Experiment

The ILL cannot pay travel and subsistence for Test experiments.

Submission of Application for Industrial Beamtime (INDU)

The ILL mission is to provide neutrons for both public and industrial research. Our Industrial Liaison and Consultancy Group (ILC) ensure rapid access and total confidentiality to industrial companies and provide a specialised staff.

All industrial research programmes are confidential and can be organized at short notice. To apply for proprietary beamtime please contact the Industrial Liaison Officers. More information can be found here.

Submission of proposals to the Deuteration Laboratory (D-Lab)


The deuteration, partial or full, of biological molecules is crucial for the full exploitation of neutron scattering studies of the structure and dynamics of macromolecular systems. The ILL operates a Deuteration Laboratory (D-Lab) as user platform within its Life Sciences Group and integrated within the Partnership for Structural Biology (PSB). The facility was set up with a number of major grants from the UK Engineering and Physical Sciences Research Council (EPSRC) and is focused primarily on the production of deuterated macromolecules (as opposed to hydrogenated analogues). From time to time it also produces 15N and 13C labelled molecules – usually for studies involving the joint use of neutron scattering and high field NMR.

Access to the Deuteration Laboratory is available to users of all member state countries (regardless of where the neutron experiment is to be carried out). Applicants will normally have an expression system of their own available. Proposals to the facility are assessed by electronic peer review. Application forms are available here; once completed, applications should be submitted to ILL’s User Office.

Proposals would typically include:

  • a description of the scientific case for the production of the material – background, rational for use of deuterated material, nature of neutron application, results anticipated
  • estimate of amount of D2O and deuterated carbon sources needed (should be discussed prior to proposal submission)

Peer review typically takes a few weeks.

[NB Applicants are strongly advised to consult Dr. Michael Haertlein prior to the submission of their proposal to discuss technical issues, feasibility, and timing before submitting their application]

Scheduling of successful proposals
Successful proposals are scheduled and allocated a local contact who will carry out the production work. The timing of the production will depend on current activity within the laboratory and this should be discussed prior to proposal submission.
In general the applicant will be provided with deuterated cell paste derived from their expression system and will themselves take responsibility for the purification and subsequent sample preparation (eg crystallisation, solution characterization etc).

Note that acceptance of a Deuteration Laboratory proposal does not in any way imply allocation of neutron beamtime. However, the beamtime allocation committee will be in possession of status information relating to deuterated sample material that is implicated in beamtime proposals.

Reimbursement of costs
The rules for proposals/expenses are identical to those applicable to beamtime requests (further information here). Access to this facility is provided free of charge for authors of accepted proposals from users of ILL member state countries. Proposals from scientists of non-member state countries may be considered but will have to cover the costs of production themselves (eg D2O, carbon source).
