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 Bio-PAC. 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 ‘HITRIplus’ are encouraged to submit their applications additionally through ‘HITRIplus’ for obtaining financial support. Note that since 2021 GSI provides access to its facilities under HITRIplus (Heavy Ion Therapy Research Integration_plus); a contract within the framework of Transnational Access (EU/Horizon2020 Integrating Activities). Please find more information here and HITRIplus.


Contact persons for the 'Call' are:

PPAC Scientific Secretary: Karin Füssel

For issues with GATE: GATE-Help

Access and support through HITRIplus: Marco Durante, Konrad Lehmann


(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.

Recent Bio-PAC Meetings


Biophysics & Radio-Biology Program Advisory Committee (Bio-PAC)

GSI/FAIR have established a Biophysics & Radio-Biology Program Advisory Committee (Bio-PAC) that evaluates experiment proposals in the areas of biophysics, radiobiology, and radiotherapy. The Bio-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 Bio-PAC meets two in two years. The Bio-PAC 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 ammount of beam time to be allotted.

Database of granted beam time

Experiments with granted beamtime (i.e. ranked A) are listed in this table. It contains experiments in the status after granting and before completion/expiry, and gives number of granted shifts.

Experiments in the reserve list have been ranked A- due to large overdraft of beamtime. They might be scheduled if beamtime becomes available. 

Data are updated before and after a beamtime block.

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).

Calls for Proposals

During the 'calls for Proposals' experiment proposals can be submitted electronically via GATE. The next 'Call' is planned for the first quarter of 2025.

'Call for Proposals' are sent to users registered in GATE and published through the users' mailinglist. For registering to this mailinglist please see the Users Webpage.

Further information on scheduling of beam time is given under the website: Scheduling, general information on beam time can be found here.

Next Bio-PAC Meeting

Date of the next Bio-PAC Meeting: June 30 - July 1, 2025
