Summary:This paper presents the operating stability diagram for atmospheric pressure non-thermal He plasma with the aim of establishing the optimum working parameters for bacterial deactivation applications. The diagram indicates that there are four regions and three different shapes for the plasma. The plasma temperature was determined via thermocouple method. The atomic and molecular species present in the plasma were identified by emission spectroscopy technique. The excitation temperature for He is around 0.2-0.25 eV. Escherichia coif cultures were deactivated successfully, results function of treatment time or gas flow-rate are presented and are compared with other sterilization techniques.
