Neoclassical Ion Transport in the Edge of Axially - Symmetric Arbitrary Cross - Section Tokamak with Plasma

چکیده
The theoretical and experimental study of the neoclassical ion transport in edge tokamak plasmas are nowadays of renewed interest. 4 In particular, these studies are important in the so-called H-regimes in large toroidal facilities, characterized by sharp gradients in the radial pro les of macroscopic plasma quantities in the region of the transport barriers. Plasmas of small tokamaks, which play an important role in investigating di erent physical phenomena in fusion research, are mainly in L-regime. Nevertheless, some problems regarding the neoclassical ion transport in these machines are not yet well understood and additional e orts are needed. One of these problems is addressed in this paper, namely the neoclassical ion transport in the edge of an axisymmetric plasma column of arbitrary crosssection and with subsonic toroidal ows. These ows can be induced by parallel neutral beam injection or by radio frequency waves. II Starting equations

Stability of the resistive wall mode in HBT-EP plasmas
A relatively simple model of the resistive wall mode RWM is derived for a large aspect ratio, low , circular cross section, tokamak plasma, surrounded by a concentric, thin, uniform resistive wall. The model employs uniform toroidal plasma rotation, and includes the following realistic edge dissipation mechanisms: dissipation due to charge-exchange with cold neutrals, and dissipation due to neo...
متن کاملEffect of flow damping on drift-tearing magnetic islands in tokamak plasmas
A systematic fluid theory of nonlinear drift-tearing magnetic island dynamics in a conventional large aspect-ratio lowcircular cross-section tokamak plasma is derived from a set of single-helicity reduced neoclassical-magnetohydrodynamical equations which incorporate electron and ion diamagnetic flows, ion gyroviscosity, poloidal and toroidal flow damping, cross flux-surface momentum and partic...
متن کاملA novel flexible field-aligned coordinate system for tokamak edge plasma simulation
Tokamak plasmas are confined by amagnetic field that limits the particle and heat transport perpendicular to the field. Parallel to the field the ionised particles canmove freely, so to obtain confinement the field lines are ‘‘closed’’ (i.e. form closed surfaces of constant poloidal flux) in the core of a tokamak. Towards, the edge, however, the field lines intersect physical surfaces, leading ...
متن کاملTheoretical interpretation of the toroidal rotation velocity observed in Alcator C-Mod Ohmic H-mode discharges
It is shown that neoclassical theory explains quite well the origin of the co-current toroidal rotation velocity measured in the core of stationary Alcator C-Mod edge localized mode (ELM)-free Ohmic high confinement (H)-mode discharges. Both edge and core toroidal rotation velocity profiles are determined to a good approximation by the edge ion temperature and density pedestals, where the gradi...
متن کاملConfinement of Injected Silicon
Results of injected impurity transport studies on the Alcator A tokamak are presented. We find that injected silicon diffuses throughout. the plasma and is then observed, contrary to the predictions of neoclassical theory, to leave the discharge, having confinement times much shorter than the discharge length. There is no observed build-up of silicon on the axis of the device. The impurity conf...
