Abstract

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)
