Title:

Energy Transport in the Steady State Plasma Sustained by DC Helicity Current Drive

Date of publication:

Jan. 1992

Key words:

DC Helicity Injection, Current Diffusivity, Steady State Tokamak, Thermal Conductivity

Abstract:

Steady state operation of tokamaks which is sustained by the DC helicity current drive near edge is studied. The necessary value of the current diffusivity is obtained. Relation between the current diffusivity and the thermal diffusivity, which are governed by the microscopic turbulence, indicates that this requires too large thermal transport for the parameters in present day experiments.
