Directed drift fluxes and electric domains in plasma

It is shown that the electric domains in a plasma are generated due to the inequality of the fluxes of the directed drift of charged particles. The time of their nucleation is approximately equal to the Maxwellian relaxation time of the space charge. It has been theoretically obtained that the frequency of space-charge waves and the time constant of the rise (decay) of oscillations during the domain instability are determined by the differential conductivity of the plasma. There are modes of electric domains generation in a gas-discharge plasma that are characteristic of a semiconductor plasma.
