STATUS OF THE DESIGN OF THE FAIR STORAGE RINGS

Three storage rings with a maximum magnetic rigidity of 13 Tm are foreseen as part of the FAIR project. They will mainly serve the preparation of intense secondary beams of antiprotons and rare isotopes, which are produced with high intensity proton and heavy ion beams, respectively. Cooling, by stochastic and electron cooling, and accumulation as well as deceleration of the secondary beams are manipulation techniques which are foreseen. Internal targets and collisions of rare isotope beams with electrons or antiprotons in a collider set-up will be employed in physics experiments studying the properties of the secondary beams. This report summarizes the latest design work for the FAIR storage rings.
