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.

Braking due to non-resonant magnetic perturbations and comparison with neoclassical toroidal viscosity torque in EXTRAP T2R

, 2015
The non-resonant magnetic perturbation (MP) braking is studied in the EXTRAP T2R reversed-field pinch (RFP) and the experimental braking torque is compared with the torque expected by the neoclassical toroidal viscosity (NTV) theory.

Neoclassical toroidal torque generation by auxiliary heating in non-axisymmetric tori

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 isotropic alpha heating) clearly cannot give rise to net forces or torques.

Demo 14-06 Oil Viscosity

, 2001
This video demonstrates the difference in viscosity between three weights of motor oil. Tubes filled with the oil, with a small bubble on top, are quickly inverted. The bubbles begin to rise, with the bubble in the least viscous oil rising most rapidly,
