Description
Accurate and stable integration of charged-particle motion in complex magnetic fields is essential for beam-dynamics simulations in accelerators and beam lines.
For the Xsuite simulation framework we have recently developed a spatially discretized Boris-like algorithm that advances particle coordinates using the longitudinal position as the independent variable.
The scheme retains the symmetric kick–rotate–kick structure of the standard time-based Boris pusher, ensuring exact preservation of the total momentum magnitude and of the phase-space volume.
We derive its formal properties using operator-splitting and backward-error analysis, showing that it is second-order accurate, and that the symplectic error scales quadratically with the integration step.
Such properties are also verified by numerical tests on representative field distributions.
