Progress in ITER Heating and Current Drive System
Recent progress in the R&D and the design work of plasma heating and current drive (H&CD) technologies for ITER are described. The H&CD systems are composed of 20 MW electron cyclotron (EC), 20 MW ion cyclotron (IC) and 33 MW negative ion based neutral beam (N-NB) systems, and design and R&D work continues for plasma commissioning. Significant progress in R&D during the preceding two years has ...
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 کاملSpectral Effects on Fast Wave Core Heating and Current Drive
RF heating and current drive is an essential component in most magnetic fusion devices, including ITER. Recent results obtained with high harmonic fast wave (HHFW) heating and current drive (CD) on NSTX strongly support the hypothesis that the onset of perpendicular fast wave propagation right at or very near the launcher is a primary cause for reduced core heating efficiency at long wavelength...

متن کاملBenchmarking of Neutral Beam Current Drive Codes as a Basis for the Integrated Modeling for ITER
This paper discusses the results of a benchmark study in which the predictions of numerical codes for neutral beam current drive and heating were compared using the parameters of the reference ITER steady state scenario, as a collaboration work of in the frame of the ITPA-SSO group. The models employed in the benchmarked codes for each physics related to NB heating and current drive, such as th...
