Magnetic field modelling and symplectic integration of magnetic fields on curved reference frames for improved synchrotron design: first steps / Van der Schueren, Silke (CERN ; U. Rome La Sapienza (main)) ; De Maria, Riccardo (CERN) ; Benedetto, Elena (Unlisted, CH) ; Barna, Daniel (Wigner RCP, Budapest) ; Migliorati, Mauro (U. Rome La Sapienza (main))
Compact synchrotrons, such as those proposed for cancer therapy, use short and highly bent dipoles. Large curvature drives non-linear effects in both body and fringe fields, which may be critical to control to obtain the desired dynamic aperture. [...]
