Solicitation of proposals for PAC Period 1 for non-proprietary research

The first FRIB Program Advisory Committee (PAC1) will consider experiments using fast, stopped, and reaccelerated beams. Detailed information regarding proposal preparation can be found on the FRIB Scientific User Portal. Proposals have page limits with required sections covering science, goals, and technical issues.

The submission deadline for the PAC1 meeting has passed. View the list of PAC-recommended experiments here.

A second call for proposals is anticipated in summer 2022, with a PAC2 meeting in March 2023.

FRIB PAC1 timeline

  • 22 November 2020 - Call for Proposals for FRIB PAC1 meeting
  • 22 February 2021 - Proposal submission deadline
  • 5-6 and 12-13 August 2021 - FRIB PAC1 Meeting
  • 20 August 2021 - List of PAC-recommended experiments posted to the FRIB website and spokespersons notified
  • 2022 (estimated) - First FRIB user experiments

Proposal evaluation

Following the Call for Proposals issued by the FRIB Laboratory Director, the PAC committee will review and evaluate the proposal submissions. The evaluation is based on:

  • The full scientific value of the results
  • The technical feasibility of the proposal
  • The ability of the collaboration to successfully conduct the proposed experiment
  • The ability of the collaboration to publish the results in a timely manner

A first and second specialist reviewer will be assigned to each proposal. There will be no oral presentations, but two weeks prior to the PAC1 meeting, the reviewers will submit their top three questions to the spokesperson. A video conference to answer the questions will be arranged one week prior to the PAC1 meeting. Proposals are also reviewed by FRIB Laboratory staff for technical feasibility and safety issues. Spokespeople will be given at least three weeks to respond to these reviews. Proposals are kept confidential at all times as allowed by State of Michigan law, but are available to FRIB operations and technical staff as needed.

Based on its evaluation, the PAC committee will make recommendations for allocation of beam to the FRIB Laboratory Director. The FRIB Laboratory Director will decide what beam time is granted. Approximately 5 percent of beam time will be reserved for discretionary experiments. Approved proposals will be valid for a two-year period.
