The large underground FAIR ring accelerator SIS100 on the northern FAIR construction site with a circumference of 1,100 meters is a central part of the future accelerator center FAIR [Facility for Antiproton Ion Research], currently being built in international collaboration at the GSI Helmholtzzentrum in Darmstadt.
The structural work for the SIS100 is completed. The ring closure of the tunnel system has been made, and the concrete layer of the last tunnel slab has been poured. It marks an important milestone in the realization process of the entire FAIR project. ion42 comprising the architectural offices DGI Bauwerk and schneider + schumacher is responsible for the conception, design and realisation of FAIR.
