Magnetic and Thermal Characteristics of a Model Dipole Magnet for the SIS 300

The synchrotron SIS 300, developed for the Facility for Antiproton and Ion Research (FAIR) project at GSI, will use fast-cycling dipoles with 100 mm inner diameter coils, magnetic field amplitude of 6 T and a ramp rate of 1 T/s. This work presents the calculations of the magnetic and thermal characteristics of a 1 m model dipole with optimized 2D and 3D geometries. AC losses in the coil and iron yoke, as well as temperature margins, were analyzed. Production tolerances for the main geometrical parameters were also studied.
