Program Advisory Committees of GSI

In GSI/FAIR's Program Advisory Committees external reviewers as internationally recognised experts in their fields give advice to the Directorate on selecting experiment proposals to grant beamtime.


General Program Advisory Committee (G-PAC) - an international program advisory committee of GSI, evaluating 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 plasmaphysics using ions and/or the Petawatt High-Energy Laser for Heavy Ion Experiments (PHELIX).


Information for Users on services and beam time can be found on the Users' Webpages

Submission of Beamtime Proposals

From 2021 on, submission of beamtime proposals to GSI is done via the platform GATE (General Access Tool to the Experimental infrastructures of GSI). 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).

Granted Experiments and Reserve List

Experiments with granted beamtime (i.e. ranked A) are listed in this table. It contains experiments in the status after granting and before completion/expiry, and gives number of granted shifts.

Experiments in the reserve list have been ranked A- due to large overdraft of beamtime. They might be scheduled if beamtime becomes available. 

Data are updated before and after a beamtime block.
