Abstract
A symplectic, symmetric, second-order scheme is constructed for particle evolution in a time-dependent field with a fixed spatial step. The scheme is implemented in one space dimension and tested, showing excellent adequacy to experiment analysis. Higher order schemes are deduced by composition.
► New algorithm to calculate accurately particle motions in given wavefields. ► Taylored to describe directly observable properties of the particle motion. ► Avoiding interpolations (used to estimate passage times in fixed timestep methods). ► Intrinsically symplectic.
