Vladimir Kornilov, "Beam Dynamics for SIS100 of FAIR and for the Future Circular Collider (FCC)"

The primary accelerator of the FAIR project, the SIS100 synchroton, will be a 1 km long ring machine, able to accelerate heavy ions to energies of 1-10 GeV/u, or protons to 29 GeV. The proton beam will consist of four bunches, 5e12 particles each. A typical SIS100 cycle will last for 3-10 sec. The Future Circular Collider (FCC), presently under consideration in a dedicated international study, should be a 100 km long proton-proton (FCC-hh) ring collider for the energy of 50 TeV. The beam should consist of ten thousand bunches, 1e11 protons each. A typical FCC cycle will last for 2 hours. Already these few parameters show big differences between these two synchrotrons. Still, there are common beam dynamics issues for SIS100 and for FCC-hh, which are important for the successful operation and thus are the subjects of active research.
