Zonal flow generation in the improved confinement mode plasma and its role in confinement bifurcations
Unstable fluctuations develop in the initially quiescent plasma in the improved confinement mode of the H-1 heliac when the radial electric field (Er) shear exceeds some critical value. These unstable Er shear-driven modes are shown to generate zonal-flow-like poloidally symmetric potential structures, similar to those generated in the low confinement mode (Shats M G and Solomon W M 2002 Phys. ...
متن کاملImproved-confinement plasmas at high temperature and high beta in the MST RFP
We have increased substantially the electron and ion temperatures, the electron density, and the total beta in plasmas with improved energy confinement in the Madison Symmetric Torus (MST). The improved confinement is achieved with a well-established current profile control technique for reduction of magnetic tearing and reconnection. A sustained ion temperature >1 keV is achieved with intensif...
متن کاملResistive tearing mode instability with shear flow and viscosity
The linear theory of the resistive tearing mode instability in slab geometry, has been recently extended by introducing the effect of equilibrium shear flow and viscosity [ Phys. Fluids 29, 2563 (1986); Phys. Fluids B 1,2224 (1989); ibid. 2,495 (1990); ibid. 2,2575 (1990) 1. In the present analysis, numerical solutions of the time-dependent resistive equations are generalized to this problem an...
متن کاملImproved Particle Confinement Mode in the H-1 Heliac Plasma.
The first experimental observation of the sudden transition to the improved particle confinement mode in the H-1 heliac is reported and shows a clear dependence on magnetic configuration. In a lowtemperature plasma a transition to improved confinement followed by a twofold increase in the electron density is observed when the magnetic field exceeds a critical value Bcr . At B ø Bcr the transiti...
متن کاملTrapped electron mode turbulence driven intrinsic rotation in Tokamak plasmas.
Progress from global gyrokinetic simulations in understanding the origin of intrinsic rotation in toroidal plasmas is reported. The turbulence-driven intrinsic torque associated with nonlinear residual stress generation due to zonal flow shear induced asymmetry in the parallel wave number spectrum is shown to scale close to linearly with plasma gradients and the inverse of the plasma current, q...
