Super ADAM, located at Institut Laue-Langevin in Grenoble, France, is Sweden's first neutron reflectometer.
The instrument is partly funded by VR, The Swedish Research Council. Swedish users will be allocated 70 % of the beamtime each year.
Applications for beamtime on Super ADAM should be submitted electronically using Electronic Proposal Submission system (EPS) via the ILL User Club. Proposals can be submitted twice a year, before the deadlines usually in February and September. If you are new to ILL please register as a new user via the User Club to have access to the EPS system.
Since Super ADAM is a part of the CRG (Collaborative Research Group) system, it is possible to obtain beamtime in two ways:
- Standard ILL beamtime (30% of total beamtime). Your proposal will be judged by an ILL Review Committee. In case of a successful application your experiment will be financially supported by the ILL (travelling, accommodation, meals).
- Super ADAM CRG beamtime (70% of total beamtime). Your proposal will be judged by the Super ADAM Review Committee. In this case proposals from Swedish institutions have priority.
Both types of proposals consist of the following parts: two-page description of the scientific case, which should be prepared in advance as a PDF file, and details about your sample (material, size, weight etc.) and sample environment (temperature, magnetic field, gas environment, solid/liquid cell etc.), which you add during the submission process. After the beamtime we can help you with the analysis of the data using different refinement programs, for example refinement with GenX.
You are welcome to contact the beamline scientists at Super ADAM as part of writing the proposal to get an idea of the feasibility, availability of equipment and resolution. The beamline scientists can also help you simulate the expected outcome of the experiment to assess the feasibility of the scientific case.

With specular reflectivity we can determine the in-plane average structure of thin films in the range of a few nanometres to hundreds of nanometres. Neutron reflectivity is commonly used to study:
- The depth distribution of light elements in soft matter such as polymer interfaces and solid/liquid interfaces.
- The depth distribution of light elements, especially hydrogen, in thin films.
- The depth resolved magnetic structure of thin films. Neutron reflectivity is sensitive to the absolute magnitude of the magnetic moment and its direction in-plane.
- In addition, looking at the diffusely scattered radiation, away from the specular direction, we can learn things about micrometre sized in plane structures (for example magnetic domains).
The instrument has two modes of operation: a low resolution − high flux and one high resolution mode. Currently we only use the high resolution mode which is mainly used for polarized neutron reflectivity.
- All the material that are published using data from Super Adam has to acknowledge VR for the financial support for funding Super Adam.
- The part of the Super Adam team that has been involved in the measurements shall be included as an author of the published material. This is due to that when we give support, to the extent desired by the user, we will engage full in the task at hand.
- All publications has to follow the Vancouver rules of conduct. (see e.g. http://www.icmje.org/index.html and http://www.codex.vr.se/en/etik2.shtml)
Authorship credit should be based on:
- Substantial contributions to conception and design, or acquisition of data, or analysis and interpretation of data
- Drafting the article or revising it critically for important intellectual content and
- Final approval of the version to be published.
Authors should meet conditions 1, 2, and 3. (from the Vancouver-rules on authorship)
