Positive column plasma in noble gases at middle pressures is analysed for stability in the frames of the linear hydrodynamic theory. At critical values of pressure and current the discharge becomes unstable to radial contraction (contraction) and to wave disturbances of the type of current pinch constrictions (contraction ionization waves). Ionization waves in the contracted discharge are three‐dimensional formations with electron concentration oscillations on the axis in the opposite phase with current pinch cross section. The discharge diffuse‐recombination theory was used for analysing the problem of instability arising.
