Dates of call for proposals, deadlines and details of submission and dates meetings

In GSI/FAIR’s Program Advisory Committees, internationally recognised experts in their fields advice the Directorate as external reviewers on the selection of experiment proposals for the allocation of beamtime.

General Program Advisory Committee (G-PAC) – evaluates experiment proposals in the fields of nuclear and atomic physics. This General PAC also acts as umbrella for the different sub-PACs like:

Biophysics & Radio-Biology Program Advisory Committee (Bio-PAC) – evaluates experiment proposals in the areas of biophysics and radio-biology.

Materials Research Program Advisory Committee (Mat-PAC) – evaluates experiment proposals in the area of materials research.

PHELIX and Plasmaphysics Program Advisory Committee (PPAC) – evaluates experiment proposals on plasma physics using ions and/or the Petawatt High-Energy Laser for Heavy Ion Experiments (PHELIX).

Call for Proposals for beamtime in 2026/2027

Experimentalists are invited to submit experiment proposals in the framework of FAIR Phase-0, which offers beamtime for experiments at GSI until the start of FAIR. The FAIR Phase-0 program is exploiting the facilities of GSI, upgraded to meet the requirements as FAIR injectors, plus the FAIR CRYRING storage ring and the PHELIX laser. Moreover, it offers an opportunity to use detectors developed for FAIR for scientific programs.

The present ‘Calls for Proposals’ all four Program Advisory Committees (PACs) together are foreseen to evaluate experiment proposals for user beamtime in 2026 and 2027 of roughly (all PACs combined):

  • 350 shifts at UNILAC,
  • 300 shifts at SIS18,
  • 250 shifts in total for at ESR, ESR-HITRAP and ESR-CRYRING,
  • 00 shifts at PHELIX.
  • For experiments at CRYRING in standalone-mode (internal ion sources only) a ‘Call’ for beamtime in 2026 will be communicated in 2025.

    For deadlines and details of the different ‘Calls’ please refer to the individual websites of the Program Advisory Committees given above.

    Detector tests: For beamtime applications for pure detectors tests in 2026/27 (i.e. w/o direct scientific goal (!), testing of detectors or similar instrumentation, in parasitic beam mode) please contact the respective PAC Scientific Secretary (e.g. M. Vogel for G-PAC) to obtain specific access and instructions for this.

    Submission of Beamtime Proposals

    Submission of beamtime proposals to GSI is done via the platform GATE (General Access Tool to the Experimental infrastructures of GSI/FAIR). With a personalized account users can submit proposals as Proposers, organize the experiment on site (Responsible Experimentalist) or participate in an experiment on the campus (Experimentalist).

    Login to GATE at: gate.gsi.de
