Three-dimensional fluid simulations are performed in a simple magnetized toroidal plasma, in which vertical and toroidal magnetic fields create helicoidal magnetic field lines that terminate on the torus vessel. The simulations are carried out in the three-dimensional flux tube that wraps around...

- Quantum recoil and Bohm diffusion. Melrose, D. B.; Mushtaq, A. // Physics of Plasmas;Sep2009, Vol. 16 Issue 9, p094508
It is argued that the inclusion of the Bohm potential in quantum fluid equations is equivalent to inclusion of a nonrelativistic form of the quantum recoil in plasma kinetic theory. The Bohm term is incorrect when applied to waves with phase speed greater than the speed of light.

The existence of a critical pressure gradient needed to drive the interchange instability is experimentally demonstrated in the simple magnetized torus TORoidal Plasma EXperiment [A. Fasoli et al., Phys. Plasmas 13, 055902 (2006)]. This gradient is reached during a scan in the neutral gas...

A recent paper [L.-N. Hau and W.-Z. Fu, Phys. Plasmas 14, 110702 (2007)] deals with certain mathematical and physical properties of the kappa distribution. We comment on the authorsâ€™ use of a form of distribution function that is different from the â€œstandardâ€ form of the kappa...

- Relativistic electron and ion dust charging currents. Tribeche, Mouloud; Boukhalfa, Soufiane // Physics of Plasmas;Sep2009, Vol. 16 Issue 9, p094502
A first theoretical attempt is made to present a relativistic generalization of the well-known orbit-limited motion theory. The appropriate relativistic (electron and ion) dust charging currents are derived. The nonlinear electrostatic potential is then expressed in terms of the variable dust...

The Childâ€“Langmuir law relates the voltage applied across a planar diode to the saturation value J[sub CL] of current density that can be transmitted through it in case the injection velocity of electrons is zero. The Childâ€“Langmuir current density J[sub CL] is, at the same time:...

- Density Transition Phenomena in Magnetized Plasma by Voltage Biasing. Shinohara, S.; Matsuyama, S.; Sugimori, K. // AIP Conference Proceedings;2003, Vol. 669 Issue 1, p236
Repeated transition phenomena (flip-flop pattern) with abrupt reductions and jumps of the electron density was observed, by the voltage biasing to an electrode in the cylindrical magnetized plasma. These global, self-excited, dynamical density transitions in bistable system were accompanied by...

- On steady poloidal and toroidal flows in tokamak plasmas. McClements, K. G.; Hole, M. J. // Physics of Plasmas;Aug2010, Vol. 17 Issue 8, p082509
The effects of poloidal and toroidal flows on tokamak plasma equilibria are examined in the magnetohydrodynamic limit. â€œTransonicâ€ poloidal flows of the order of the sound speed multiplied by the ratio of poloidal magnetic field to total field BÎ¸/B can cause the (normally...

In this Brief Communication, it is shown that an analytical solution for an exact two-dimensional X- or Y-line equilibrium may be constructed quite easily on the basis of the fundamental theoretical equation. The equilibria discussed in the present report show the potential for a rich variety of...
