Abstract：Grouping up many individual plasma jets to construct jet arrays is an effective way to enlarge the downstream treatment area of a single plasma jet, while the stability and uniformity of jet array are essential for its industrial application. In this paper, in order to obtain a stable and uniform jet array, a 1D atmospheric pressure plasma jet array in He is generated driven by a nanosecond pulse source, and its discharge characteristics are investigated with optical and electrical diagnoses including images and voltage-current waveforms. The influence of pulse parameters such as voltage amplitude, rising time and pulse frequency on discharge characteristics is studied, and the optimal pulse parameters for generating a uniform jet array are obtained, with the results being analyzed. Results show that a uniform 1D He plasma jet array can be generated under proper pulse parameters with the ring-ring electrode structure. Increasing the voltage amplitude has little effect on discharge uniformity, but can increase the discharge energy, transported charge and plume length, thus improve the discharge strength of jet array. The rising time has slight effect on discharge energy, transported charge and uniformity, and the pulse frequency significantly influences the uniformity, while has little effect on discharge energy and transported charge. The non-uniformity of jet array is due to the non-uniform distribution of electrical field and different content of residual active particles in each channel. Decreasing pulse frequency can reduce the influences of residual active particles on the discharge and is thus beneficial for obtaining a uniform jet array.
