General Program Advisory Committee (G-PAC)
The General PAC is an international program advisory committee of GSI and FAIR with external experts as members. The General PAC gives advice to the Directorate on selecting experiment proposals that are submitted by individual users or user groups in the areas of nuclear and atomic physics, currently for the FAIR Phase-0 program. Following periodic calls for proposals, the General PAC meets to evaluate those experiment proposals on the basis of scientific merit and with regard to the GSI/FAIR strategy, and advises the GSI/FAIR Scientific Director on the amount of beamtime to be approved.. The G-PAC also acts as umbrella for the different sub-PACs of GSI/FAIR for various research fields.
Since 2021 we are using a new platform for proposal and user management: The General Access Tool to the Experimental facilities of GSI / FAIR (GATE).
Registration to GATE under: https://gate.gsi.de.
GATE Short Manual for Users: here
Registration in GATE is possible independant of an open 'Call' at any time and registered users will be informed on new 'Calls'. So it is advisable for interested users to register any time.
All (!) participants of a proposal and experimentalists coming on-site for the experiment need to be registered in GATE (and allow being visible for other users' search in GATE).
During proposal submission the Proposer is explicitly asked to indicate host lab resources required for the proposed experiment additional to beamtime requests. Related to preparations for FAIR, technical and infrastructure departments often have very tight time schedules and need to plan carefully with respect to time and manpower. In order to offer the best possible service enabling the experiments to be set up and run in an optimal way, we need to know all requirements to us as host lab in advance.
In the webform you are asked to mark whether and which resources you will need, incl. further specifications on this request. This will allow the involved departments to confirm the feasibility. Together with your local contact person, you can restrict your information there to a minimum and best guesses from experience or after consulting the department involved. In case of doubts, the respective department will come back to you with further questions before confirming feasibility of your experiment.
While this information in the proposal serves as rough information only, when planning the execution of your experiment you need to contact the respective host department directly and with concrete details on your requirements.
We absolutely want to avoid the situation in which after evaluation and granting we discover, that the proponents had expected service of GSI, which cannot be delivered (at the required time/in that detail or volume) and thus a granted experiment cannot run.
Note on Research Data Management Plan
A Research Data Management Plan (RDMP) is currently not mandatory, but users are asked to plan ahead of time how to take, manage, process and store their data, and think about its possible later publication. This also helps in formulating a request for host lab resources, e.g. IT support, if required. For more information see this document.
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.
Further information on application and scheduling of beam time is given under the websites Applying for Beamtime and Scheduling, respectively. General information on beam time can be found here.

G-PAC Scientific Secretaries
Presently, there is no meeting of the committee planned, nor is there any open 'Call for Beamtime Proposals'.
Users registered in GATE indicating their interest in our facilities will be informed on new calls.
