Self Organization Processes in Fusion Burning Plasmas*

The presence of self-organization [1] in well confined plasmas was recognized originally [1] on the basis of the radial profiles of the thermal diffusion coefficients derived from relevant experiments. Thus the principle of ``profile consistency'' was proposed, and later, amply reconfirmed and applied to plasma pressure profiles. The radial profiles of the spontaneous rotation velocities investigated in recent years have required [2] the introduction of an inflow velocity, with a ``profile consistency'' feature, in the angular momentum transport equation. In experiments on plasmas close to ignition conditions self-organization should persist, given the variety of factors involved. Then it is justifiable to use transport model based on ``profile consistency,'' such as the so-called Coppi-Tang model [3], in order to simulate plasmas that Ignitor and ITER [3] should produce. *Sponsored in part by the US DOE.\\[4pt] [1] B.
