Effects of Neoclassical Tearing Modes and Toroidal Field Ripple on Lost Alpha Power in the SPARC Tokamak

, 2022
Submitted for publication in Plasma Physics and Controlled FusionUsing the SPIRAL Monte Carlo, full particle-orbit simulation code [Kramer PPCF 2013], we investigate the effects of neoclassical tearing modes (NTMs) and toroidal field (TF) ripple on alpha

Neoclassical offset toroidal velocity and auxiliary ion heating in tokamaks

, 2016
In conditions of ideal axisymmetry, for a magnetized plasma in a generic bounded domain, necessarily toroidal, the uniform absorption of external energy (e.g., RF or any isotropic auxiliary heating) cannot give rise to net forces or torques. Experimental

Spectra of magnetic perturbations triggered by pellets in JET plasmas [PDF]

, 2010
Aiming at investigating edge localised mode (ELM) pacing for future application on ITER, experiments have been conducted on JET injecting pellets in different plasma configurations, including high confinement regimes with type-I and type-III ELMs, low ...

Physical Mechanism Determining the Radial Electric Field and its Radial Structure in a Toroidal Plasma [PDF]

, 1994
Radial structures of plasma rotation and radial electric field are experimentally studied in tokamak, heliotron/torsatron and stellarator devices. The perpendicular and parallel viscosities are measured.

Effects of neoclassical toroidal viscosity on plasma flow evolution in the presence of resonant magnetic perturbation in a tokamak

Effects of neoclassical toroidal viscosity (NTV) on plasma flow evolution in the presence of resonant magnetic perturbation (RMP) in a tokamak have been evaluated using a cylindrical theory model. Calculations show that the introduction of NTV has almost no effect on the flow on the resonant surface, so the locked or unlocked state on the resonant ...

Effects of Electron-Cyclotron-Resonance-Heating-Induced Internal Kink Mode on the Toroidal Rotation in the KSTARTokamak

, 2018
It is observed that the magnitude of the toroidal rotation speed is reduced by the central electron cyclotron resonance heating (ECRH) regardless of the direction of the toroidal rotation.
