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

Applications for Beamtime
Proposals for beamtime are submitted to GSI/FAIR via the plattform GATE (gate.gsi.de). Depending on the research field the respective Program Advisory Committees (PAC) then will evaluate the applications 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:
It is recommended that all users register in GATE as user-specific information 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) (www.gsi.de/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.
