PHELIX and Plasmaphysics Program Advisory Committee (PPAC)

The PHELIX and Plasmaphysics Program Advisory Committee (PPAC) is an international program advisory committee of GSI/FAIR. It gives advice to the Directorate on selecting experiment proposals that are submitted by individual users or user groups in the field of plasma physics with ions and lasers, currently for the FAIR-Phase 0 program. Following periodic calls for proposals, the PPAC meets approx. once every year; it evaluates the 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 Scientific Director.

'Call for Proposals at PHELIX' - is closed

The 'Call for Proposals' for experiments with the high-energy/high-power laser PHELIX between autumn 2024 and summer 2025 closed on November 07, 2023.

Experiments at our laser facility Petawatt High-Energy Laser for Heavy Ion EXperiments (PHELIX) cover a variety of research fields, e.g. atomic physics, plasma physics, extreme matter physics, laser-particle acceleration. In the last call, experiment proposals for the laser were accepted and a total of approx. 170 shifts of PHELIX beamtime were to be offered corresponding to roughly 8 to 9 experiments.This call did not include experiments with ions!



  • It is advisable to start proposal submission early and discuss it before final submission with your Link Scientist.
  • All participants of a proposal need to be registered in GATE and added as 'Co-Proposers' to the proposal.
  • Experiments granted before 2021 have to be submitted in an updated version and will be re-evaluated by the PPAC.

For more information on submission of PHELIX proposals via GATE please see below (Application Procedure) and here: Information for PHELIX users.

For information on beamtime planning and scheduling at PHELIX see: Beamtime Planning at PHELIX.

Laser and experiment parameters are given under

GATE platform

Since 2021 we are using the General Access Tool to the Experimental facilities of GSI/FAIR (GATE) as platform for proposal and user managment.

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' searches in GATE).

For more information on submission of PHELIX proposals via GATE please see: Information for PHELIX users.
