Abstract：The spectra of helium dielectric barrier discharge jet are measured and analyzed using emission spectrometry at atmospheric pressure. Firstly, the types of active particles in the jet are studied by using coaxial dielectric barrier discharge method. Secondly, the spectral intensity variation laws under different gas flow rates, different peak voltages and different axial distances are studied. Finally, the electron excitation temperature in the jet is studied. The findings reveal that the primary active particles include He I, N2 (C3∏u-B3∏g), N2+(B2∑u+-X2∑g+), ·OH and oxygen free radical. As the helium flow rate increases, the spectral intensity of the active particle spectral lines initially rises and then falls. Conversely, as the peak voltage increases, the spectral intensity of these lines intensifies. As the axial distance increases, except for the continuous decrease in the intensity of the ·OH spectral line, all other spectral lines show a weakening-strengthening-weakening trend. Using the double spectral line method, the electron excitation temperature for two selected spectral lines of He I is calculated to be between 600 K and 1 200 K. Overall, the electron excitation temperature rises with increasing peak voltage and falls with increasing helium gas flow rate.
