Frequency scaling of the lower-hybrid-current-drive density limit in tokamak plasmas.
It is shown experimentally that the lower-hybrid current drive "density limit" is a function of the rf source frequency. While in previous 800MHz experiments this limit occurred at ie = 6 x 1012 cm-3. with a newly installed 2.45GHz, 100kW rf system on the Versator II tokamak fully rf-driven discharges have been achieved at densities up to i = 1.Ox 1013 cm3 , without increasing the toroidal magn...
متن کاملLower hybrid current drive at densities required for thermonuclear reactors
For the progress of the thermonuclear fusion energy research based on the tokamak concept, it is essential to drive current non-inductively in high-density plasmas for producing steady state, thermally well insulated, stable and large volume plasmas. ITER (International Tokamak Experiment Reactor), as an example, will have relatively high densities at the periphery of the plasma column (ne_0.8 ...
متن کاملCurrent drive at plasma densities required for thermonuclear reactors.
Progress in thermonuclear fusion energy research based on deuterium plasmas magnetically confined in toroidal tokamak devices requires the development of efficient current drive methods. Previous experiments have shown that plasma current can be driven effectively by externally launched radio frequency power coupled to lower hybrid plasma waves. However, at the high plasma densities required fo...
متن کاملModeling of Plasma Rotation in Radio-Frequency-Wave-Heated Tokamak Plasmas
It is shown by considering the general properties of solution of the kinetic equation that plasma rotation in Radio-Frequency (RF) wave heated tokamak plasmas can be modeled by the RF-modified plasma viscous force. This approach is qualitatively different from a model that uses a radial current to model the RF effects on plasma rotation. 52.55.Fi Typeset using REVTEX
متن کاملElectron cyclotron current drive efficiency in an axisymmetric tokamak
The neoclassical transport theory is applied to calculate electron cyclotron current drive (ECCD) efficiency in an axisymmetric tokamak in the low-collisionality regime. The tokamak ordering is used to obtain a system of equations that describe the dynamics of the plasma where the nonlinear ponderomotive (PM) force due to high-power RF waves is included. The PM force is produced around an elect...
