Electrical Conductivity of a Highly Turbulent Plasma

Abstract

The electrical conductivity of a highly turbulent plasma is measured in the electron density range ${10}^{10}$-${10}^{13}$ ${\mathrm{cm}}^{-3\mathrm{}}$, using hydrogen, argon, and xenon. When the applied electric field is large (≳ 100 V ${\mathrm{cm}}^{-1\mathrm{}}$), it is found that the conductivity may be described by the formula $\sigma \approx \frac{1}{2}{\left(\frac{M}{m}\right)}^{\frac{1}{3}}{\omega }_{\mathrm{pe}}$, which was first suggested by Buneman.
