The HESR (High Energy Storage Ring) is an essential part of the Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt. It will be used in antiproton as well as in heavy ion operation modes. The latter is the main topic of the current study. The storage ring employs electron and stochastic cooling methods which helps to significantly reduce beam size, divergence and momentum spread. The energy of about 5 GeV per nucleon is foreseen for bare uranium. This all results in unprecedented conditions for high-precision internal target experiments with heavy ion beams. The experimental program will be carried out in the framework of the SPARC (Stored Particle Atomic Physics Collaboration) project.
In this study an ion optical layout designed specifically for the HESR operating with heavy ions is presented. The nonlinear beam dynamics simulations are carried out and the results are discussed.
