Stabilization of Rotating Plasma

Abstract

The interchange instability of rotating plasma is investigated from the thermodynamic point of view. The rotation of plasma tends to stabilize itself in the negative δY configuration, where Y=∫(r²⁄B)dl⁄∫(1⁄B)dl. In the negative δ∫(1B⁄)dl configuration with negative δY property the rotating plasma is more stable than the non-rotating one. An example of the negative δY configuration is exhibited.
