Toroidal modeling of the effect of resonant q95 on n = 1 error field penetration in EAST

Nuclear Fusion
The plasma response to the n  = 1 resonant magnetic perturbation in EAST has been systematically investigated using the MARS-F/Q codes, focusing on the roles of q _95 and $\beta_\mathrm N$ in error field penetration.

Comparison of Parallel Viscosity with Neoclassical Theory [PDF]

Toroidal rotation profiles are measured with charge exchange spectroscopy for the plasma heated with tangential NBI in CHS heliotron/torsatron device to estimate parallel viscosity. The parallel viscosity derived from the toroidal rotation velocity shows

Dependence of neoclassical toroidal viscosity on the poloidal spectrum of applied nonaxisymmetric fields

Nuclear Fusion, 2016
Abstract This paper presents a single mode model that accurately predicts the coupling of applied nonaxisymmetric fields to the plasma response that induces neoclassical toroidal viscosity (NTV) torque in DIII-D H-mode plasmas. The torque is measured and modeled to have a sinusoidal dependence on the relative phase of multiple ...

Neoclassical transport in enhanced confinement toroidal plasmas [PDF]

, 1996
It has recently been reported that ion thermal transport levels in enhanced confinement tokamak plasmas have been observed to fall below the irreducible minimum level predicted by standard neoclassical theory.

Flux–force relation for non-axisymmetric tori in general flux coordinates and neoclassical toroidal plasma viscosity

, 2010
Flux–force relation, a fundamental relation that relates transport fluxes to forces, for non-axisymmetric tori in general magnetic flux coordinates that are not Hamada coordinates, is derived.

Plasmonic toroidal metamaterials at optical frequencies

, 2012
Toroidal dipole is created by currents flowing on a surface of a doughnut-shaped structure along its meridians first considered by Zel'dovich in 1957 [1]. Toroidal metamaterials were first theoretically proposed in 2007 [2].

Effects of the applied magnetic field phasing on the neoclassical toroidal viscosity and toroidal rotation in JT-60SA

, 2017
Error field correction coils (EFCCs) will be installed in JT-60SA to apply the perturbed magnetic field for avoidance of the locked mode and control of the edge localized modes (ELMs).

Neoclassical Toroidal Viscosity Calculations in Tokamaks Using a δf Monte Carlo Simulation and Their Verifications [PDF]

, 2011
Neoclassical toroidal viscosities (NTVs) in tokamaks are investigated using a δf Monte Carlo simulation, and are successfully verified with a combined analytic theory over a wide range of collisionality.

Observation of parallel viscosity in a stellarator [PDF]

, 1991
Damping of the plasma toroidal velocity owing to parallel viscosity is observed in the Compact Helical System-torsatron device with tangential neutral-beam injection. The toroidal velocity profile is dominated by perpendicular viscosity when the magnetic-
