Abstract
We have experimentally studied the coherence of oscillations appearing, as a result of the Buneman instability, in a stationary regime of a diaphragme d discharge between hollow electrodes. The degree of coherence of the oscil lations grows with the discharge current intensity, which is probably expla ined by an electrostatic coupling between discharge channels increasing wit h the amplitude of oscillations.
