One of the primary challenges in plasma confinement in tokamaks is the escape of energetic particles at the plasma edge, which can lead to significant energy losses. The flux of these particles is closely linked to the equilibrium magnetic configuration of the tokamak and the influence of electric and magnetic perturbations in the plasma.

This study investigates the impact of different configurations of electric and magnetic fields in the transport characteristics of the plasma. An area-preserving map, derived from a Hamiltonian description of particle dynamics, was used to describe particle orbits. This map allowed the construction of Poincaré sections, representing the intersection of a particle's orbit with a toroidal section of the tokamak. These sections enable detailed analysis of the system’s dynamic behavior under different conditions.
