The FAIR complex will be constructed to the east of the existing
GSI facility. The fact that the project will use the existing accelerator
as an injector influenced the decision to build the new facility here. The
architectural plan also incorporates the need to conform to radiation protection
requirements and optimize costs for the buildings and technical facilities.
All these considerations have led to the following concept:
The large double ring with a circumference of 1,100 meters will
be laid out underground in a ring tunnel at a maximum depth of 17 meters. Thus the forest
in the region of the double ring can be mostly preserved. All of the other buildings will be arranged south of the large ring tunnel.
Due to the large areas involved, an above-ground solution is more economical
here. Construction of the above-ground buildings will require clearing of
presumably 20
hectares of forest for which compensating measures have already been settled.
