Abstract
A hydrogen plasma of density ~ 1016 cm-3 and electron temperature
~ 200 eV has been investigated under electric fields of 100 to
500 V/cm. A pinch of pinch ratio ~ 3 was found to be hydrodynamically
stable for ~ 2~s during which the experiment was performed. A sharp
burst of runaway electrons of total current of the order of amperes
occured and disappeared shortly after conduction began. Large low
frequency oscillations believed to be ion-acoustic oscillations appear
and give rise to very high resistivities in qualitative agreement with
recent,theories on plasma conductivity.
