Teaching content

Heat, particle and momentum transport in the plasma are not determined only magnetic field structure but have strong nonlinearity and interaction in space. This is because the turbulence causing these transports can be strongly affected by the curvature and shear of the electric field (E×B flow) and the magnetic field. The relationship between the spatial structure of radial electric field (ExB flow) and magnetic field and the transport of the plasma is studied.
