Abstract

Apparatus for maintaining three-dimensional MHD equilibrium in a plasma contained in a helical axis stellerator includes a resonant coil system, having a configuration such that current therethrough generates a magnetic field cancelling the resonant magnetic field produced by currents driven by the plasma pressure on any given flux surface resonating with the rotational transform of another flux surface in the plasma. Current through the resonant coil system is adjusted as a function of plasma beta.

Method and apparatus for maintaining equilibrium in a helical axis stellarator

Patent Reiman, A ; Boozer, A

A method is described of maintaining three-dimensional MHD equilibrium of a plasma contained in a helical axis stellarator. The stellarator has a set of primary coils. The method comprises: providing a current through a resonant coil system about the stellarator. The resonant coil system has a configuration such that the current therethrough generates a magnetic field cancelling the resonant magnetic field, B/sub 1/, produced by currents driven by the plasma pressure at any given flux surface resonating with the rotational transform, chi, of another flux surface in the plasma; and varying the current as a function of ..beta.., where ..beta..=2p/submore »« less
Helical axis stellarator equilibrium model

Technical Report Koniges, A E ; Johnson, J L

An asymptotic model is developed to study MHD equilibria in toroidal systems with a helical magnetic axis. Using a characteristic coordinate system based on the vacuum field lines, the equilibrium problem is reduced to a two-dimensional generalized partial differential equation of the Grad-Shafranov type. A stellarator-expansion free-boundary equilibrium code is modified to solve the helical-axis equations. The expansion model is used to predict the equilibrium properties of Asperators NP-3 and NP-4. Numerically determined flux surfaces, magnetic well, transform, and shear are presented. The equilibria show a toroidal Shafranov shift.

Flexible helical-axis stellarator

Patent Harris, J H ; Hender, T C ; Carreras, B A ; ...

In a helical-axis stellarator of the type including a planar circular central winding, a planar toroidal magnetic field generating coils disposed about the central winding whose centers are located on a helical axis twisting about and spaced from the central winding to form a toroidal helix having M toroidal periods in which a helical axis plasma is magnetically confined, the improvement is described comprising: an 1=1 helical winding, where 1 is the toroidal winding multiplicity, disposed to spiral about and encompass the planar circular central winding one revolution for each period of the toroidal helix in close proximity to themore »« less
Flexible helical-axis stellarator

Patent Harris, Jeffrey H ; Hender, Timothy C ; Carreras, Benjamin A ; ...

An 1=1 helical winding which spirals about a conventional planar, circular central conductor of a helical-axis stellarator adds a significant degree of flexibility by making it possible to control the rotational transform profile and shear of the magnetic fields confining the plasma in a helical-axis stellarator. The toroidal central conductor links a plurality of toroidal field coils which are separately disposed to follow a helical path around the central conductor in phase with the helical path of the 1=1 winding. This coil configuration produces bean-shaped magnetic flux surfaces which rotate around the central circular conductor in the same manner asmore »« less
