We describe a new apparatus for magnetic confinement of a pure ion plasma, with laser diagnostics to measure test particle transport across the magnetic field. In addition to the axisymmetric trapping potential, rotating electrostatic wall perturbation is used to counteract the plasma loss processes, giving steady-state ion confinement for weeks. Electronic spin polarization of the ion ground s...

The successful development and optimization of fusion power sources will depend largely upon learning more about plasma turbulence and its relation to transport. Gaining a greater knowledge of plasma-edge turbulence is key, as the transport of particles near the plasma's edge has a profound effect on global plasma confinement. It is in this region that the boundary values for plasma temperature...

Noncentral heavy ion collisions lead to the production of a quark gluon plasma with angular momentum. We investigate, using holographic AdS (anti--de Sitter)/QCD models, how does rotation medium affects confinement/deconfinement transition temperature ${T}_{c}$. In this is represented by Hawking-Page process involving two asymptotically spaces. The here extending approach anti--de Sitter spaces...

A favorable regime of H-mode confinement, seen on the Alcator C-Mod tokamak is described. Following a brief period of ELM-free H-mode, the plasma evolves into the Enhanced D-Alpha (EDA) H-mode which is characterized by very good energy confinement, the complete absence of large, intermittent type I ELMs, finite impurity and majority species confinement, and low radiated power fraction. Accompan...

The fluctuation-induced dynamo effect, resulting from the correlation between electron pressure fluctuation and radial magnetic in core, is measured by an cyclotron radiometer Faraday-effect polarimetry high-temperature tokamak plasmas. acts to flatten parallel current core of a confinement fusion device.
