III International Symposium on Toroidal Plasma Confinement

Classical impurity ion confinement in a toroidal magnetized fusion plasma.

High-resolution measurements of impurity ion dynamics provide first-time evidence of classical ion confinement in a toroidal, magnetically confined plasma. The density profile evolution of fully stripped carbon is measured in MST reversed-field pinch plasmas with reduced magnetic turbulence to assess Coulomb-collisional transport without the neoclassical enhancement from particle drift effects....

Plasma confinement by circularly polarized electromagnetic field in toroidal geometry

A novel plasma confinement concept based on plasma confinement by electromagnetic pressure of circularly polarized electromagnetic fields is proposed. Practical implementation of this concept in a toroidal device is suggested. In this concept the confining field frequency is in the lower range such that the size of the device is much smaller than the vacuum wavelength. Most of the previous radi...

Overview of Magnetohydrodynamics Theory in Toroidal Plasma Confinement

The biggest challenges mankind ever faces are falling energy sources and food shortages. If controlled nuclear fusion were achieved with net energy yield, the energy source problem would be solved. If natural photosynthesis were reproduced, food shortage concern would be addressed. Though both nuclear fusion and photosynthesis are universal, the difficulties to achieve them are disproportionall...

Toroidal Momentum Confinement in Tokamaks

Theories for the toroidal momentum confinement in tokamaks have been developed. It is shown that the logarithmic gradient of the toroidal flow is a linear combination of logarithmic gradients of the plasma pressure and the temperature in neoclassical quasilinear theory. The fluctuation-induced toroidal stress consists of a diffusion flux, a convective flux, and a residual flux. The effects of a...
