One Dimensional D.C. Resistivity Due to Strong Low Frequency Turbulence.

Abstract

A theoretical model is presented showing the effects of finite amplitude ion cavities on the d.c. conductivity of a collisionless one-dimensional plasma. A 20% ion cavity is shown to prevent the acceleration of 50% of the plasma electrons. The effect is independent of cavity width and spacing so that in the case of localized, spiky turbulence, rms ion density fluctuations of a few percent can significantly modify the d.c. response. The theoretical predictions are compared with both particle and Vlasov computer simulations. (Author)
