Call for proposals

The ILL is dedicated to helping its visiting researchers to make the most of its facilities. Neutron beams and instrument access are provided free of charge for proposers of accepted experiments.

Call for proposals

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.

Cancellation of Autumn 2017 proposal round

The ILL will not be able to operate the reactor cycle originally planned to start on October 23. Due to the resulting backlog of experiments, the first two cycles in 2018 will be used to perform experiments already accepted in April 2017.
We have therefore decided to cancel the current proposal round. Proposals for experiments in the second half of 2018 should be submitted in the spring proposal round.

Policy for beamtime allocation: "two-thirds rule"

Proposals with non-member country proposers will be guaranteed a chance of being accepted only if they are part of a collaboration and at least two-thirds of the proposers are from a member country (or from the ILL).
NEW: This will no longer be a blocking condition for proposal submission: limited beamtime (less than 5% of the overall available) will be granted to proposals not complying with this rule on the basis of scientific excellence.

Industry-sponsored academic research

In order to demonstrate the 'innovation potential' of neutron scattering, we are particularly keen to know if your academic research is directly linked to industry. This is most obvious if you have industry sponsorship, for example, for students or samples. Please use the tick-box on the proposal form and give appropriate information in the text box, including when possible the name of the company you are working with. ILL would like to use this information to promote the use of neutrons by industry via academia.

Director's discretionary time (DDT)

5% of ILL beam time is reserved for proposals that do not fall within the usual rules of proposal submission.
Primarily these proposals concern urgent experiments that cannot wait for the twice-yearly proposal rounds. Proposals can be submitted at any time and they will be reviewed by the chair and relevant members of the proposal sub-committee concerned and the ILL science director. If successful, beam time will then be awarded on the requested instrument as soon as possible.
New : DDT may also be used to award beam time to excellent proposals which do not satisfy the rule in which two-thirds of the proposers must come from ILL's Associate and Scientific Member countries (see two-thirds rule below). These proposals can therefore be submitted by any team with an excellent idea for an experiment and this must be done through the usual proposal rounds so that the level of excellence can be judged by comparison with other proposals.

EASY access

We remind you that room temperature, powder diffraction measurements on the high resolution diffractometer can be requested at any time.

More information on the various type of access can be found here.

 

Scheduling period

The proposals accepted at this round will be scheduled in 2018.
The dates of the reactor cycles are announced here.

 

Instruments available

The following instruments will be available for the forthcoming round. You will find details of the instruments here.

  • powder diffractometers: D1B*, D2B, D20, SALSA
  • disordered materials diffractometer: D4
  • polarised neutron diffractometers: D3, D23*
  • single-crystal diffractometers: D9, D10
  • large scale structure diffractometers: D19, LADI
  • small-angle scattering: D11, D22, D33
  • reflectometers: SuperADAM*, D17, FIGARO
  • small momentum-transfer diffractometer: D16
  • diffuse-scattering spectrometer: D7
  • three-axis spectrometers: IN1-LAGRANGE, IN8, IN12*, IN20, IN22*, ThALES
  • time-of-flight spectrometers: IN4, IN5, IN6-SHARP*, BRISP*
  • backscattering and spin-echo spectrometers: IN11, IN13*, IN15, IN16B
  • nuclear-physics instruments: PN1
  • fundamental-physics instruments: PF1B, PF2, S18*
  • fission product prompt gamma-ray spectrometer: FIPPS

* Instruments marked with an asterisk are CRG instruments, where a smaller amount of beamtime is available than on ILL-funded instruments, but we encourage applications for these.

 The list of operating CRGs is as follows (status September 2017):

  • CRG-A: D1B, IN13, IN6-SHARP (from September 2017)
  • CRG-B: BRISP, D23, SuperADAM, IN12, IN22, S18
  • CRG-C (no public beam time available): GRANIT jointly funded with LPSC (UJF, CNRS)

NEW: Within a collaboration between ILL and the LLB, IN6 will be upgraded using certain components of the LLB instrument FA#.
From September 2017, IN6 will become SHARP, a CRG-A instrument and only 50% of the available beamtime will be available through the ILL user programme.


Updated list of environment codes

We have appended new codes for the environment equipment available at the ILL. In particular, a wider choice is now available for those experiments to be performed close to ambient conditions. We would appreciate very much that you take the time to check this list to identify the codes which best match your needs.
