Description

This paper presents the development of a symplectic integrator for particle tracking in insertion devices at SIRIUS. The method relies on analytical field representations specifically tailored to model the magnetic structure of the device accurately. Tracking results obtained with the new integrator are compared with those from traditional kickmaps, and the differences observed in dynamical aperture calculations and frequency map analyses are examined, showing the integrator’s effect on long-term beam dynamics predictions. The integrator is further applied to specify the field roll-off requirements for SIRIUS’s first CPMU, which will operate with a minimum gap of 4.65 mm at a high-beta section.
