Fundamental Studies on Turbulent Heating of a Fusion Plasma
Abstract
During the past year the investigation has continued of the scaling laws of turbulent heating and on optimizing the experiment as a pulsed plasma heating device. Three main conclusions have been reached from these investigations: The plasma resistivity is anomalously large during turbulent heating, approaching the Buneman value normally associated with the electron 2- stream instability, yet the observed turbulent spectrum is more appropriate for ion acoustic waves; the ion energy distribution is non-Maxwellian, but nearly isotropic. The ions have a small drift in one direction, and a high energy tail in the opposite (electron drift) direction; the turbulent heating often limits itself before the peak of the current is reached.
