Experimental characterization of large-scale structures in the turbulent states of a toroidal plasma device
A common feature of nonlinear models for electrostatic turbulence in plasmas is that the energy develops, at least partly, towards small wave numbers, called 'inverse energy cascade'. The resulting large scale coherent structures play an important role as a saturation mechanism of turbulence as well as in anomalous transport processes. Experimentally several campaigns focused on the detection and characterization of large scale structures in the density and plasma potential fluctuations. They came to different conclusions. The question is whether the specific form of the coherent structures depends on the magnetic field geometry or if it is determined by other plasma properties.
