Operation of a heavy ion beam probe (HIBP) on a reversed field pinch is unique from other toroidal applications because the magnetic field is more temporal and largely produced by plasma current. Improved confinement, produced through the transient application of a poloidal electric field which leads to a reduction of dynamo activity, exhibits gradual changes in equilibrium plasma quantities. A...

The proposal for tritium-suppressed D-D fusion and the understanding of the turbulent pinch in magnetically confined plasma are new developments in fusion science that create an alternate and potentially advantageous technology pathway. Tritiumsuppressed D-D fusion eliminates the need to breed fuel from lithium, reduces the damage from 14 MeV neutrons, and allows structural materials now qualif...

Male and female rainbow trout were segregated into high- and low-responding individuals (HR, LR) on the basis of their plasma cortisol response to a 3-h period of confinement imposed at monthly intervals for 5 months. Consistent divergence was obtained in the responsiveness of the two groups, although the difference between LR and HR groups was greater in female fish (56 c.f. 116 ng ml(-1)) tha...

Nuclear fusion has arisen as an alternative energy to avoid carbon dioxide emissions, being the tokamak a promising nuclear fusion reactor that uses a magnetic field to confine plasma in the shape of a torus. However, different kinds of magnetohydrodynamic instabilities may affect tokamak plasma equilibrium, causing severe reduction of particle confinement and leading to plasma disruptions. In ...

Finite two-dimensional dust clusters are systems of a small number of charged grains. The self-confinement of dust clusters in isotropic plasmas is studied using the particle-in-cell method. The energetically favorable configurations of grains in plasma are found that are due to the kinetic effects of plasma ions and electrons. The self-confinement phenomenon is attributed to the change in the ...

Formation of internal transport barriers (ITBs) in a plasma is a key to access to improved confinement. In JT-60U, there are two types of plasmas which are accompanied with ITB. One is a high Bo plasma and the other one is a reversed magnetic shear (RS) plasma. In RS plasmas, interesting features can be seen in spatial profiles of plasma parameters. For example, the location of the ITB can be s...
