چکیده انگلیسی
The synchrotron SIS100 is one of the two basic accelerators of the future Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt. This accelerator should provide high intensity U28+ and proton beams with a pulse repetition rate of 1Â Hz (i.e. a ramp rate of 4Â T/s). The magnetic system of the accelerator uses superferric 2.1Â T dipoles of about 3Â m length and 32Â T/m quadrupoles of about 1Â m length. The magnet coils are made of a hollow tube cable wrapped with Cu/NbTi composite wire cooled with two phase helium flow at 4.5Â K. The bore dimensions were defined to 130Â ÃÂ 60Â mm for the dipole and 135Â ÃÂ 65Â mm for the quadrupole. We present the developed ANSYS models for different important aspects: AC loss, magnetic field quality and mechanical stability. Preliminary studies verified the approaches and these models were applied to calculate the effects for the coil, the yoke and the beam pipe structures. We outline further steps to fully describe the SIS100 magnets including mechanical and thermal properties.
