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.
