Plans approved for FAIR ring accelerator



The Hesse Ministry for the Environment, Energy, Agriculture and Consumer Protection has issued three further partial construction permits for the new accelerator facility FAIR. Thus the construction plans for several buildings have been confirmed taking into account technical and safety-relevant details. Among these is, above all, the centerpiece of the facility, the ring accelerator SIS100.

Now that the general approval for the new accelerator complex FAIR has been granted, the detailed construction plans for the individual buildings are currently being examined and approved by the official agencies in Hesse. In addition to the massive ring accelerator, which will have a circumference of 1100 meters, the experimental area for biophysics and material research and the facility for the creation of new isotopes, the super fragment separator, have been approved. In previous examinations a storage ring, infrastructure buildings and large sections of the beam controls were approved. The Hesse Ministry confirmed in a document that the detailed planning of the building complies with the safety regulations for the scientists and technicians working there, and also for the immediate environment.

The approval processes are being overseen by GSI Helmholtzzentrum für Schwerionenforschung GmbH on behalf of FAIR GmbH.

The international particle accelerator complex FAIR, which is some 4000 meters long and largely underground, is to be erected as an extension of the existing GSI facility, which is some 400 meters long and which will serve as an injector in the future. More than 3,000 scientists from over 50 countries will conduct research on the building blocks of matter and the development of the universe. In this respect particularly intensive precision beams of antiprotons and ions of all chemical elements can be created at FAIR.
