Information for our users

Approximately 1.000 scientists (called users) from all over the world visit GSI/FAIR per year to conduct experiments at the accelerator facility in the frame of FAIR Phase-0, and publish their discoveries. Before the start of FAIR, this program exploits the accelerator facilities of GSI, which have been upgraded in view of the requirements as FAIR injectors. FAIR-Phase-0 also allows the use of detectors, which have been developed for FAIR, plus the new FAIR CRYRING storage ring.

In addition to our users a large number of scientists come to GSI/FAIR as long-term guests in the framework of cooperations in research and development.

Furthermore GSI/FAIR host a variety of conferences and meetings regularly attended by many international guests.

Our guest-scientists find all relevant information for their stay on the following pages.

Applications for Beamtime

Depending on the research field proposals for beamtime can be submitted to one of the four Program Advisory Committees (PACs) of GSI/FAIR through the plattform GATE ( The PACs will evaluate the proposals and recommend the Scientific Director to grant beamtime. More information is given on the PACs' webpage, where links lead to the sub-pages of each individual committee:

All users should register in GATE as user-specific information to users will be communicated to those persons.

Welcome Office

The central point of contact for associated guests and users on campus is the Welcome Office (WEO) ( Registering there before arrival at GSI is requested. This helps preparing a number of issues in advance, and to reduce the time spent on formalities when entering the campus.

The webpage of WEO also contains a special checklist for COVID-19 related measures when entering the GSI/FAIR campus.
