The Physics Basis of ITER Confinement
ITER will be the first fusion reactor and the 50 year old dream of fusion scientists will become reality. The quality of magnetic confinement will decide about the success of ITER, directly in the form of the confinement time and indirectly because it decides about the plasma parameters and the fluxes, which cross the separatrix and have to be handled externally by technical means. This lecture...
متن کاملCT/P-06 Collective Modes and Fast Particle Confinement in ITER
The results of numerical models have been compared to the existing data to investigate damping mechanisms, check parametric dependencies and extrapolate the existing experimental results to reactor conditions that remain inaccessible to present day tokamaks. Stabilising mechanisms involving mode conversion to kinetic Alfvén waves have been identified. The comparison between theory and experimen...
متن کاملPower requirements for superior H-mode confinement on Alcator C-Mod: Experiments in support of ITER
Power requirements for maintaining sufficiently high confinement (i.e., normalized energy confinement time H 98 ≥1) in H-mode and its relation to H-mode threshold power scaling, P th , are of critical importance to ITER. In order to better characterize these power requirements, recent experiments on the Alcator C-Mod tokamak have investigated H-mode properties, including the edge pedestal and g...
متن کاملITER overview
The article summarizes six years of technical work carried out by the ITER Joint Central Team and Home Teams under the terms of the ITER Engineering Design Activities (EDA) Agreement. The major products of this effort are as follows: a comprehensive and detailed engineering design with supporting assessments, cost estimates and a schedule based on industrial studies; a comprehensive safety and ...
متن کاملStabilization of Burn Conditions in an ITER FEAT like Tokamak with Uncertainties in the Helium Ash Confinement Time
In this work we demostrate using a two-temperature volume averaged 0D model that robust stabilization, with regard the helium ash confinement time, of the burn conditions of a tokamak reactor with the ITER FEAT design parameters can be achieved using Radial Basis Neural Networks (RBNN). Alpha particle thermalization time delay is taken into account in this model. The control actions implemented...
