Abstract
The lowest frequency mode of the ion-acoustic instability in a high-current low-pressure wall-confined discharge, which serves as an active medium of cw ion gas lasers, is studied experimentally. The dispersion relation for this mode is obtained using the spectral correlation analysis of spontaneous plasma emission. The dependences obtained are compared with the available theoretical models of ion-acoustic instability in low-pressure discharges.
