The Relationship Between ∫dl/B and dV/dΨtor

  • Chapter
Flux Coordinates and Magnetic Field Structure

Abstract

In many elementary discussions it is “proved” in an intuitive manner that the specific volume \( \dot V(\Psi _{tor} ) \equiv dV/d\Psi _{tor} \) equals the closed line integral ∮dl/B. That this is true only in an approximate sense, and that a distinction is to be made between rational and irrational surfaces is discussed in the authoritative review paper by Solov’ev and Shafranov (1970). For completeness, we reproduce their arguments in this Chapter albeit converted to our notation.
