Experimental results are presented on ionization processes in the vibrationally non‐equilibrium flow of CO preliminarily heated by a shock wave and adiabatically cooled in the supersonic nozzle with a flow Mach number of M = 3.9. It is shown that for a wide range of flow stagnation temperatures, the value of the recorded semi‐self‐maintained current considerably exceeds the one due to thermal gas ionization in the plenum chamber.
