Fast Wave Current Drive on Diii - D
The physics of electron heating and current drive with the fast magnetosonic wave has been demonstrated on DIU-D , in reasonable agreement with theoretical modeling. A recently completed upgrade to the fast wave capability should allow f id noninductive current drive in steady state advanced confinement discharges and provide some current density profile control for the Advanced Tokamak Program...
متن کاملRadial transport and electron-cyclotron-current drive in the TCV and DIII-D tokamaks.
Calculation of electron-cyclotron-current drive (ECCD) with the comprehensive CQL3D Fokker-Planck code for a TCV tokamak shot gives 550 kA of driven toroidal current, in marked disagreement with the 100-kA experimental value. Published ECCD efficiencies calculated with CQL3D in the much larger, higher-confinement DIII-D tokamak are in excellent agreement with experiment. The disagreement is res...
متن کاملDivertor Plasma Physics Experiments on the Diii–d Tokamak
DIVERTOR PLASMA PHYSICS EXPERIMENTS ON THE DIII–D TOKAMAK. In this paper we present an overview of the results and conclusions of our most recent divertor physics and development work. Using an array of new divertor diagnostics we have measured the plasma parameters over the entire divertor volume and gained new insights into several divertor physics issues. We present direct experimental evide...
متن کاملTH/P3-1 Off-axis Neutral Beam Current Drive for Advanced Scenario Development in DIII-D
Modification of the two existing DIII-D neutral beam lines is proposed to allow vertical steering to provide off-axis neutral beam current drive (NBCD) as far off-axis as half the plasma radius. New calculations indicate very good current drive with good localization off-axis as long as the toroidal magnetic field, BT, and the plasma current, Ip, are in the same direction (for a beam steered do...
