An Atmospheric Cold Plasma Jet With a Good Uniformity, Robust Stability, and High Intensity Over a Large Area

To gain a cold atmospheric pressure helium plasma jet with good uniformity, robust stability, and high intensity over a larger area, a novel dielectric barrier discharge plasma jet generator with a honeycomb-like powered electrode and a gas shielding is proposed in this paper. The innovative design has been demonstrated to facilitate more homogeneous treatment and a higher degree of insusceptibility in plasma stability to variations of samples in their material properties, physical dimensions, and structures.
