Cross-Field Anomalous Resistivity Associated with the Lower-Hybrid-Drift Instability in Strongly Inhomogeneous Plasmas

  • Ronald C. Davidson
Part of the Nobel Symposium Committee (1976) book series (NOFS, volume 36)


The cross-field anomalous resistivity associated with the lowerhybrid-drift instability is investigated. Particular emphasis is placed on the low-drift-velocity regime characterized by rLi/2∆Ln~ < 1, where rLi=vici. is the ion Larmor radius, and ∆Ln =−(∂ℓnN/∂x)−1 is the length scale for density inhomogeneity. The predicted value of anomalous resistivity (for Te ≪ Ti,) is \({\eta _{AN}} = 4\pi {(\pi /2)^{1/{2_{{\Omega _{LH}}}} - 1{\varepsilon _F}}}/N{T_i}\) where ΩLHpi/(1+ω pe 2 ce 2 )1/2 is the lower hybrid frequency, and \({\varepsilon _F} = < \delta {\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle\thicksim}$}}{E} ^2} > /8\pi\)
