A Lower Hybrid Current Drive System for ITER
A 20 MW/5GHz Lower Hybrid Current Drive (LHCD) system was initially due to be commissioned and used for the second mission of ITER, i.e. the Q=5 steady state target. Though not part of currently planned procurement phase, it is now under consideration for an earlier delivery. In this paper, both physics and technology conceptual designs are reviewed. Furthermore, an appropriate work plan is als...
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 کاملElectron cyclotron current drive calculated for ITER conditions using different models
The current drive efficiency for the ITER reference Scenario-2 has been calculated by the newly developed ray-tracing code TRAVIS for both the upper and equatorial launcher. For comparison, two adjoint approach models are applied, the high-speed-limit model and a model with the parallel momentum conservation taken into account. It is shown, that in the angle range expected as optimal launch ang...
متن کاملBenchmarking of Lower Hybrid Current Drive Codes with Application to
This paper discusses the results of a benchmark exercise in which the predictions of several simulation models for lower hybrid current drive (LHCD) were compared using parameters typical of the steady state operating scenario in the ITER device (the so-called Scenario 4). The most complete LHCD simulation models that were used combined 2D velocity space Fokker Planck solvers with toroidal ray ...
