The efficiency of toroidal devices for plasma confinement, such as tokamaks and stellarators, is limited by turbulent processes and instabilities that can lead to magnetic field lines and charged particle escapes. To analyze the phenomena occurring during confinement, we can describe the systems using a Hamiltonian approach, reducing the problem to the study of symplectic maps. Different …
Investigate the propagation of oscillations in the Texas Helimak and tokamak TCABR and their control by modifying the equilibrium electric field. Determine the main oscillations characteristics and their influence on the particle chaotic transport, especially the formation of shearless transport barriers. (AU)
Symplectic maps are a useful tool to describe the behavior of magnetic field lines in plasmas confined within toroidal devices like Tokamaks. The efficiency of Tokamaks are inherently tied to the confinement improvement, which can be achieved by the transport barriers within the plasma and by the chaotic region formed on the edge by the employment of magnetic limiters. Both the barriers a…
