Materials Research Program Advisory Committee (Mat-PAC)

GSI/FAIR have established a Materials Research Program Advisory Committee (Mat-PAC) that evaluates experiment proposals in the area of materials research. The Mat-PAC members give advice to the GSI/FAIR directorate on selecting experiment proposals that are submitted by individual users or user groups, currently for the FAIR-Phase 0 program. Following periodic calls for proposals, the Mat-PAC meets to evaluate 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.

'Call for Proposals' - closed

We hereby invite you to submit experiment proposals in the framework of FAIR Phase-0, which offers beamtime for experiments at GSI until the start of FAIR. This includes proposals on technical improvements. Scientific experiment proposals will be evaluated by the Program Advisory Committees. The FAIR Phase-0 program will exploit the facilities of GSI, which have been upgraded to meet the requirements as FAIR injectors, plus the FAIR CRYRING storage ring. Moreover, FAIR Phase-0 will be an opportunity to use detectors developed for FAIR.

The present Call for Proposals for the Mat-PAC is foreseen to offer a total user beamtime (counted as main shifts) in 2023 and 2024 of roughly

  • 120 shifts at UNILAC,
  • 25 shifts at SIS18,
  • 12 shifts at ESR, HITRAP and CRYRING,
  • 11 shifts at CRYRING standalone.

Your proposals must be submitted by the 30th of June 2022 - Submission is closed!

A list of typically available beam parameters can be found here.

We regret to inform you that currently, participants with Russian or Belarussian affiliation cannot be participants in experiment proposals at GSI/FAIR.

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:

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).
