Benchmarking 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 ...
متن کاملA 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 کاملNumerical Studies and Simulation of the Lower Hybrid Waves Current Drive by using Fokker – Planck Equation in NSST and HT-7 Tokamaks
Recent experiments on the spherical tokamak have discovered the conditions to create a powerful plasma and ensure easy shaping and amplification of stability, high bootstrap current and confinement energy. The spherical tours (ST) fusion energy development path is complementary to the tokamak burning plasma experiment such as NSTX and higher toroidal beta regimes and improves the design of a po...
