General Program Advisory Committee (G-PAC)

The General PAC is the international program advisory committee of GSI with external 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. 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 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 for various research fields.

Database of granted beamtime

For information on remaining shifts/proposals of approved experiments a database of active proposals can be searched, where entries are updated at the end of each beamtime block.
