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 technical feasibility and with regard to the GSI/FAIR strategy, and makes recommendations on the amount of beam time to be allotted by the directorate. The G-PAC also acts as umbrella for the different sub-PACs of GSI/FAIR for various research fields.
Call for proposals for experiments at CRYRING in 'standalone' mode
Within the physics programme of FAIR Phase-0, we call for experiment beamtime proposals at the CRYRING@ESR ion storage ring with use of its internal ion sources only.
Available are most ions that can be produced in a small, 10 GHz EZR ion source with at least 0.1 euA. Experiments can be conducted for beam rigidities between 0.1 and 1.4 Tm. To find all ions that have been stored in CRYRING@ESR so far see
https://www.gsi.de/work/forschung/appamml/atomphysik/anlagen_und_experimente/cryringesr
All other ions require prior test and development time.
This call is situated within the call for beamtime 2023/24 with the available experiment beamtime during May / June 2024 and a total of roughly 100 shifts including machine setup for CRYRING in 'standalone' mode ('CRY-intern'). Proposals are to be submitted via the GATE system at
for evaluation by the General Program Advisory Committee (G-PAC) of GSI / FAIR, for details see www.gsi.de/g-pac
Deadline is the 15th of December 2023. A short manual for the GATE portal can be found here:
https://www.gsi.de/fileadmin/GF-wiss/GATE_short_manual_User.pdf
Participants with Russian or Belarussian affiliation are currently exempt from proposing and participating in experiments at GSI/FAIR.
Proposals consist of the forms to be filled within the GATE system and a PDF file for which instructions can be found here:
https://www.gsi.de/g-proposal_structure
We ask you to consult the Link Scientist of the experiment site in question (see also the form 'Technical Requirements' in GATE) well before submission of the application. This is to ensure technical feasibility of your experiment and meaningful entries in the GATE forms on the details of your planned experiment. After submission, correcting your request is not possible. Please consider that close to the submission deadline the Link Scientists might not be available, so please avoid last-minute actions.

GATE platform
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).
