A stratification wave was excited by weak square-wave modulation of the discharge current using a pentode, and by a very short voltage pulse applied to the external electrode near the cathode. A narrow metal ring was placed outside a discharge tube. Pulses of 1 mu sec were applied to the ring, and oscillographs of the light intensity in the positive column excited by striation motion were made. The experiment indicated that a stratification wave can originate any place in an originally homogeneous positive column if the stationary state of the processes in the plasma is externally perturbed in this place, independently of the boundary regions of the discharge (T.R.H.)
