Geodesic acoustic modes with poloidal mode couplings ad infinitum
Rameswar Singh, Ö D Gürcan, X Garbet +4
Geodesic acoustic modes (GAMs) are studied, for the first time, including all poloidal mode couplings using drift reduced fluid equations. The nearest neighbor coupling patte…
PoPe (Projection on Proper elements) for code control: verification, numerical convergence and reduced models. Application to plasma turbulence simulations
T Cartier-Michaud, P Ghendrih, Y Sarazin +9
The Projection on Proper elements (PoPe) is a novel method of code control dedicated to 1) checking the correct implementation of models, 2) determining the convergence of numerica…
Anomalous dynamical scaling in anharmonic chains and plasma models with multiparticle collisions
Pierfrancesco Di Cintio, Roberto Livi, Hugo Bufferand +3
We study the anomalous dynamical scaling of equilibrium correlations in one dimensional systems. Two different models are compared: the Fermi-Pasta-Ulam chain with cubic and quarti…
A new ICRF scenario for bulk ion heating in D-T plasmas: How to utilize intrinsic impurities in fusion devices in our favour
Y. O. Kazakov, J. Ongena, D. Van Eester +5
A fusion reactor requires plasma pre-heating before the rate of deuterium-tritium fusion reactions becomes significant. In ITER, radiofrequency (RF) heating of 3He ions, additional…
Trapped-Electron Runaway Effect
E. Nilsson, J. Decker, N. J. Fisch +1
In a tokamak, trapped electrons subject to a strong electric field cannot run away immediately, because their parallel velocity does not increase over a bounce period. However, the…
Design and RF measurements of a 5 GHz 500 kW window for the ITER LHCD system
Julien Hillairet, J. Achard, N. Dechambre +13
CEA/IRFM is conducting R\&D efforts in order to validate the critical RF components of the 5 GHz ITER LHCD system, which is expected to transmit 20 MW of RF power to the plasma. Tw…
