The Extreme Light Infrastructure ERIC

Experiment proposal workflow

Three steps to beamtime

Under the Excellence-Based Access mode, Access is granted free of charge following competitive evaluation of the excellence and scientific merit of Experiment Proposals by ELI’s Programme Advisory Committee and assessment of their technical and safety feasibility. Results of Experiments performed as part of this Access process should be published and made open. The Programme Advisory Committee consists of independent experts appointed by ELI responsible for evaluating the excellence and scientific merit of the Experiment Proposals submitted to ELI via the ELI ERIC User Portal and for providing advice on the Proposals that should be awarded Access to the ELI Facilities.



  • Step 1 – Submission: Proposals for Experiments should be submitted solely via the ELI ERIC User Portal, using the dedicated submission form (add link). Proposal submission should be done only by the Principal Investigator on behalf of the Experimental Team and is subject to acceptance of the Terms and Conditions for Access and GDPR Information Notice. The submission includes a description of the Scientific and Technical Content of the Proposal for which a dedicated template should be used. For more details on registration to the User Portal, see below.
  • Step 2 – Feasibility Assessment: Proposals, once submitted, are immediately assessed by authorised ELI Staff to confirm their technical and safety feasibility. Users are strongly encouraged to contact the ELI Staff indicated as contact persons for each instrument ahead of submission to assess feasibility.
  • Step 3 – Peer-review: the scientific merit of Proposals is assessed by the ELI Programme Advisory Committee, which consists of independent scientific experts. The PAC provides advice to the ELI management by assigning a score and a rank to the Proposals.

The status and outcome of the evaluation of Proposals will be communicated via the User Portal and email notifications to the Principal Investigators without undue delay.
