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' now open

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 PPAC is foreseen to offer a total user beamtime (counted as main shifts) in 2023 and 2024 of roughly

  • 3,5 shifts at UNILAC,
  • 17 shifts at SIS18,
  • 100 shifts at PHELIX.

Your proposals must be submitted by the 30th of June 2022.

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

For current laser and experimental parameters see here.

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

Please note that GSI/FAIR now employs a website-based submission system called GATE. Each participant of a proposal is required to register1 in GATE before submission can take place. Please follow the instructions on the GATE platform and in the short GATE manual carefully. In particular, we urgently ask you to consult the Link Scientist of the experimental site in question as soon as possible to discuss technical details and feasibility of the experiment, and for guidance during the application. The Link Scientist is to be chosen within the GATE forms and can be contacted e.g. via GATE upon a first draft completion of form in the step ”Submit”. A pdf file describing the proposed experiment is to be uploaded; details on its structure and content are given here.

The filling in of the GATE online forms and attachment of a proposal PDF file can be paused and continued at any point before submission, it is hence recommended to begin the process as early as possible. The GATE website is largely self-explanatory, should you yet encounter problems in GATE, please contact GATE-Help(at)


GATE website:


Your submitted proposals will be evaluated by the PPAC. Following the recommendation by the review panel, the Scientific Management Director will grant beamtime2. The applicants will be informed on results in due time. Beamtime granted in this round will expire after 2024.

We are looking forward to an exciting science program in FAIR Phase-0!


Applicants eligible to the European program 'Laserlab Europe' are encouraged to submit their applications additionally through Laserlab Europe for obtaining financial support. Note that the application will be supported through the 5th installment of Laserlab: Laserlab V offers financial support for researchers from Europe and to some extend also for users from non-EU countries.

Further details on the process from application until running of the experiment are given on the PHELIX web page:

(1) All participants of a proposal need to register themselves and allow being searchable for other users. General Data Protection Regulation GDPR apply according to Art. 13 and 14 DSGVO: Staff Management Board GDPR english

(2) Beamtime is granted at no charge within the framework of the Helmholtz Association: "Rahmenrichtlinie über die Nutzung von Forschungsanlagen der Helmholtz-Zentren durch Dritte” (1.3.2000), §II. 1.2. GSI/FAIR need to report to funding agencies on user operation and user communities in form of statistical data.

Please note that GSI does not cover the consumables and investments necessary for running an experiment.
