AbstractLow temperature, non-equilibrium plasma was generated during gliding arc discharge in a multi-electrode reactor at atmospheric pressure. Various diagnostic methods to determine electrons and gas temperature were used. Hot electrons’ temperature has been determined by optical spectroscopy. In the case of gas temperature, which is much lower, it was determined directly by the thermovision camera to avoid tedious calculations from the spectral lines. The results of the plasma diagnostics generated by gliding arc for different process gases and their flow rates are presented and discussed. Simplified diagnostic method would be very perspective for monitoring of various technological processes where plasma is used such as treatment of flue gases, wastes utilization, deodorization, disinfection and sterilization, material processing and new material manufacturing for application in microelectronics and nanotechnologies.
