The new radioactive ion beam facility is planned as part of the project of a new international accelerator facility. These new accelerators shall serve several user communities from different fields of physics, namely nuclear structure and nuclear astrophysics, hadron studies with antiprotons, investigations of compressed nuclear matter, compressed macroscopic matter in plasmas, atomic and applied physics. The existing GSI accelerators will be extended by two new synchrotrons SIS 100 and SIS 300 for high intensity and higher energy primary beams of protons and heavy ions. Radioactive ion beams will be produced and separated in‐flight with a new fragment separator called Super‐FRS providing fragments to three experimental areas: fast in flight beams, slowed down or stopped rare isotopes and radioactive ions stored in one of the new storage rings CR and NESR. © 2004 American Institute of Physics
