The pinch effect explains turbulent transport in tokamaks
The pinch effect of the particles, which is observed in all tokamaks, furnishes the key to the selection of dominant turbulence modes. The concept of a turbulent uniform distribution of particles over some phase-space surfaces specified by the geometry of the magnetic field and by invariants is introduced. Large-scale electrostatic modes lead to a turbulent uniform distribution nq = const with a maximum particle density at the center of the column. They also lead to a natural explanation of the self-consistency of profiles. These modes can be transformed to the greatest extent by radial electrostatic fields, in accordance with the phenomenology of L-H-VH transitions. © 1994 American Institute of Physics.
