A study of the propagation of moving striations in inert gases by means of artificial feedback

A study is made of the propagation of moving striations in inert gases. The method elaborated in 6] combined with the optical method of photo-multipliers was used. The results of the measurements show that despite the fact that the striations themselves move from anode to cathode, their propagation takes place in the opposite direction. Measurements with artificial feedback further confirmed the conclusions reached in 1] and 2] on the mechanism of self-excitation of the striations by means of feedback over the external discharge circuit.In conclusion the authors thank Prof. V. Kunzl and M. Novák for valuable remarks and K. Jakoubková for help in the experiments.
