Rv. Vasil'Eva et al., Local plasma parameters and integral characteristics of a magnetogasdynamic channel under conditions of ionization instability, TECH PHYS, 45(8), 2000, pp. 1081-1084
Results are presented from an experimental investigation of the onset of io
nization instability in a disk-shaped Faraday magnetogasdynamic channel att
ached to a shock tube. The experiments were carried out in a pure inert gas
(xenon) without alkaline additives. A relation is found between the integr
al plasma characteristics of a nonequilibrium magnetogasdynamic channel and
the local parameters of a plasma that is unstable against the ionization i
nstability. Mechanisms for amplifying perturbations and increasing the effe
ctive conductivity are revealed. It is concluded that these effects stem ma
inly from the features of three-body recombination in rare gases. (C) 2000
