Three Dimensional Multiphysics Modelling of Helicon Wave Heating and Antenna Plasma Coupling for Boundary Density Control in Toroidal Fusion Plasmas
Hua Zhou, Lei Chang, GuoSheng Xu +5
Active control of scrape off layer density is emerging as a critical requirement for improving ion cyclotron resonance heating and enabling high performance steady state operation…
Simulation of convective transport during frequency chirping of a TAE using the MEGA code
Hooman Hezaveh, Yasushi Todo, Zhisong Qu +2
We present a procedure to examine energetic particle phase-space during long range frequency chirping phenomena in tokamak plasmas. To apply the proposed method, we have performed…
Magnetohydrodynamic normal mode analysis of plasma with equilibrium pressure anisotropy
M. Fitzgerald, M. J. Hole, Z. S. Qu
In this work, we generalise linear magnetohydrodynamic (MHD) stability theory to include equilibrium pressure anisotropy in the fluid part of the analysis. A novel 'single-adiabati…
First evidence of Alfven wave activity in KSTAR plasmas
M. J. Hole, C. M. Ryu, M. H. Woo +4
We report on first evidence of wave activity during neutral beam heating in KSTAR plasmas: 40 kHz magnetic fluctuations with a toroidal mode number of n=1. Our analysis suggests th…
Wave modelling in a cylindrical non-uniform helicon discharge
L. Chang, M. J. Hole, J. F. Caneses +3
A radio frequency (RF) field solver based on Maxwell's equations and a cold plasma dielectric tensor is em- ployed to describe wave phenomena observed in a cylindrical non-uniform…
A flowing plasma model to describe drift waves in a cylindrical helicon discharge
L. Chang, M. J. Hole, C. S. Cormac
A two-fluid model developed originally to describe wave oscillations in the vacuum arc centrifuge, a cylindrical, rapidly rotating, low temperature and confined plasma column, is a…
