Equilibrium Equation of Plasma with a Closed Helical Magnetic Axis.

The plasma boundary in Single Helical Axis RFP plasmas

Single Helical Axis (SHAx) states obtained in high current reversed field pinch (RFP) plasmas display, aside from a dominant mode in the m=1 spectrum, also a dominant m=0 mode, with the same toroidal mode number as the m=1 one. The two modes have a fixed phase relationship. The island chain created by the m=0 mode across the reversal surface gives rise, at shallow reversal of the toroidal field...

A multichannel magnetic probe system for analysing magnetic fluctuations in helical axis plasmas.

The need to understand the structure of magnetic fluctuations in H-1NF heliac [S. Hamberger et al., Fusion Technol. 17, 123 (1990)] plasmas has motivated the installation of a sixteen former, tri-axis helical magnetic probe Mirnov array (HMA). The new array complements two existing poloidal Mirnov arrays by providing polarisation information, higher frequency response, and improved toroidal res...

Adiabatic Equation of State and Ionization Equilibrium of Dense Plasma

We consider the adiabatic equation of state for partially ionized non{ideal plasma. Plasma isentropes are calculated with the Pad e technique in the chemical picture. The interplay of ionization/dissociation equilibrium and non{ideality is investigated.

Plasma equilibrium equations in coordinates connected with magnetic surfaces . Exact equilibrium solutions .

A representation of the static MHD equilibrium system in coordinates connected with magnetic surfaces is suggested. It is used for producing families of non-trivial 3D exact solutions of isotropic and anisotropic plasma equilibria in different geometries, with and without dynamics, and often without geometrical symmetries. The ways of finding coordinates in which exact equilibria can be constru...
