摘要: In this contribution, two examples of the turbulence interface formation are shown. The first example is at edge transport barrier (ETB) in tokamak plasmas. Because radial electric field structure formation, spatial strongly modified. A model describing how profile modification occurs examined. second formed by a coexisting pair instabilities observed linear magnetized plasma. Probe measurement reveals that linearly driven drift wave excites steep gradient parallel ion flow, which secondarily raises flow shear mode, so-called D’Angelo mode. Although habitats these modes separated radius, they oscillate simultaneously correlating with each other. Due to such dynamics, an different self-consistently appears.
