Self-consistent current motion of electrons and ions in high-current plasma channel

This paper analyses a self-consistent current motion of charged particles in high-current plasma channel. Application of the results obtained to real current channels is possible provided that pair collisions do not considerably affect the current motion of plasma charged particles and the depth of the current layer is small as compared to the channel radius. The approximation adopted in this paper can be considered to be true, for instance, in the case of hydrogen channels with millimeter radius and electron energy of the order of 10 keV provided that the plasma concentration in them is in the range of 10/sup 17/ cm/sup -3/
