Neoclassical transport in high {beta} tokamaks [PDF]

, 1992
Neoclassical, transport in high [beta] large aspect ratio tokamaks is calculated. The variational method introduced by Rosenbluth, et al., is used to calculate the full Onsager matrix in the banana regime. These results are part of a continuing study of the high [beta] large aspect ratio equilibria introduced in Cowley, et al.

How Competitive Is Myanmar's Rice Sector? A Comparison of Production Costs and Efficiency

Agribusiness, EarlyView.
ABSTRACT This paper analyzes the cost competitiveness of rice production in Myanmar by examining production costs, cost efficiency, and the potential effect of improving cost efficiency on the country's global competitiveness. To achieve this, we conduct a comparative analysis of production costs among major rice‐producing countries and estimate the ...

Turbulent Contributions to Ohm's Law in Axisymmetric Magnetized Plasmas [PDF]

, 2017
The effect of magnetic turbulence in shaping the current density in axisymmetric magnetized plasma is analyzed using a turbulent extension of Ohm's law derived from the self-consistent action-angle transport theory. Besides the well-known hyper-resistive

Neoclassical flows in deuterium-helium plasma density pedestals

, 2017
In tokamak transport barriers, the radial scale of profile variations can be comparable to a typical ion orbit width, which makes the coupling of the distribution function across flux surfaces important in the collisional dynamics.

Neoclassical transport of isotropic fast ions [PDF]

Physics of Fluids B: Plasma Physics, 1990
A study of radial gradient-driven neoclassical transport of fast ions, produced by an isotropic source in an axisymmetric toroidal system, is presented. The governing equation is a flux surface averaged Fokker–Planck equation that retains both the effects of the pitch angle scattering and drag.

Comparable levels of turbulent and neoclassical transport of high-Z impurities: integrated modelling in AUG, JET and C-Mod

Nuclear Fusion
Operation with beam heating is prone to central accumulation of high- Z impurities in present-day tokamaks due to a dominant neoclassical pinch. Fusion reactors are expected to have a different core transport regime for high- Z impurities, where ...
