Title:

Refined Theory of Diamagnetic Effect in Stellarators

Date of publication:

Aug. 1992

Key words:

stellarator, diamagnetic measurements, plasma equilibrium

Abstract:

The difference delta Phi between toroidal magnetic flux Phi_p through the plasma cross-section and the same flux Phi_v of a vacuum magnetic field is calculated analytically for "conventional" stellarators with planar circular axis. It has been done without limitations of aspect ratio, shape and position of a plasma. The results obtained show weak dependence of delta Phi/Phi_p on the geometry of equilibrium configuration. It proves that diamagnetic measurements can be considered as a reliable basis for the direct evaluation of stored plasma energy at various experimental conditions.
