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.


Please note: Since 2021 we are using a new platform for proposal and user management: The General Access Tool to the Experimental facilities of GSI (GATE).Registration to GATE under:

GATE Short Manual for Users: here

Registration in GATE is possible independant of an open 'Call' at any time. All Participants of a proposal or Experimentalists cling on-site for the experiment need to be registered in GATE. For more information on submission of PHELIX proposals via GATE please see below (Details on 'Call' and on Submission) and here: Information for PHELIX users.

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

The 2021-'Call for Proposals' at the high-energy/high-power laser PHELIX for beamtime from summer 2022 to spring 2023 closed on September 28, 2021.  Please note that this call does not include experiments with ions; a ‘call’ for those is planned for 2022.

Groups working in the fields of atomic physics, plasma physics, extreme matter physics, and laser-particle acceleration were invited to submit research proposals for beamtime at PHELIX (target stations at PHELIX, Z6 and (new) HHT).

Should questions on technical feasibility, safety issues etc. arise after submission, the proposers will be contacted to clarify these points before the advisory committee meeting. In their meeting on December 6-7, 2021, the PPAC will discuss the received proposals with a clear focus on scientific excellence and strategic issues. Questions arising in those discussion will be communicated to the proposers asking for a response within days. Accordingly, the PPAC will formulate their evaluation and recommend granting beamtime  to the Scientific Directorate.


(New) Application Procedure

Proposals were to be submitted through the new platform GATE (General Access Tool to the Experimental Infrastructures of GSI), where registered users can see all proposals in which they are involved - unsubmitted, active and finished ones – and get information on their open tasks. It was highly recommended to start editing a proposal well in advance to get acquainted with GATE!

Editing a proposal could be interrupted any time and continued later. Instructions in GATE and in the GATE Short Manual for Users lead through the process - to be followed. For any problems with the system please contact GATE-Help.

Besides specifying technical and saftely relevant details on the beamtime request, a PDF file on the scientific case and results expected, summarizing the scientific justification, and including a sketch of the setup was to be uploaded (Instruction on Proposal Structure). Applicants were urgently asked to consult their Link Scientist (formerly: local contact person) on details of the proposal and entries in the forms well before submitting the proposal (e.g. one month before deadline): Close to the deadline the Link Scientist might not be available and no corrections can be done after submission.

Note: ALL participants of a proposal (= Co-Proposer) need to register in GATE and mark in their settings that they permit appearing in other users’ search results. Thus, during editing the proposal the Proposer could add them to the respective proposal.


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.


For current laser and experimental parameters see here.

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