Blob-induced toroidal momentum transport in simple magnetized plasmas
The link between toroidal flows and density blobs is experimentally demonstrated in TORPEX simple magnetized plasmas: momentum is transferred from an ideal-interchange mode to density blobs. The phase shift between the toroidal flow and the density perturbations observed in the interchange mode where the blob is born is conserved along the blob radial trajectory. This leads to dipolar structure...
متن کاملConvective cells and blob control in a simple magnetized plasma.
Blob control by creating convective cells using biased electrodes is demonstrated in simple magnetized toroidal plasmas. A two-dimensional array of electrodes is installed on a metal limiter to obtain different biasing schemes. Detailed two-dimensional measurements across the magnetic field reveal the formation of a convective cell, which shows a high degree of uniformity along the magnetic fie...
متن کاملHigh- and low-confinement modes in simple magnetized toroidal plasmas.
Three-field simulations of interchange turbulence are presented for a simple magnetized toroidal plasma with a vertical magnetic field. The simulations show the presence of two turbulent regimes characterized by low (L) and high (H) confinement properties. We evaluate analytically the properties of the L regime, obtaining expressions for the plasma gradients and for the density and heat fluxes ...
متن کاملTurbulence and Transport in Simple Magnetized Toroidal Plasmas
Progress in understanding turbulence and related cross-field transport of fusion relevance is achieved in the simple magnetized plasmas of the TORPEX toroidal device, which provides an ideal test bed for code benchmarking and theory validation. In TORPEX (R = 1 m, a = 0.2 m), a small vertical magnetic field Bz< 4 mT is superposed on a toroidal magnetic field Bt < 100 mT, resulting in open helic...
متن کاملNondiffusive suprathermal ion transport in simple magnetized toroidal plasmas.
We investigate suprathermal ion dynamics in simple magnetized toroidal plasmas in the presence of electrostatic turbulence driven by the ideal interchange instability. Turbulent fields from fluid simulations are used in the nonrelativistic equation of ion motion to compute suprathermal tracer ion trajectories. Suprathermal ion dispersion starts with a brief ballistic phase, during which particl...
