Anomalous plasma resistivity in prepulsed flashlamp discharges

Abstract

It is shown that the V‐i characteristic of discharges in flashlamps operating in the prepulsed mode at high current densities follows the relationship V=K₀i^0.85. This result is interpreted in terms of the Sagdeev‐Galeev anomalous resistivity due to current‐driven ion‐acoustic turbulence.
