This study focuses on the generation and loss of reactive oxygen species (ROS) in low-temperature atmospheric-pressure rf (13.56MHz) He+O2+H2O plasmas, which are of interest for many biomedical applications.
Summary form only given. Recent studies have shown that atmospheric pressure radio- frequency glow discharges (RF-APGD) have the potential to replace costly vacuum plasma processing systems. Unlike low pressure discharges the highly collisional nature of atmospheric pressure plasma introduces an inherent plasma instability RF-APGD exhibits a tendency to undergo a glow-to-arc transition (GAT) when...
The pulsed excitation of a discharge is investigated in this study for large-scale low-temperature plasma generation. A uniform glow-like discharge is obtained by reducing the duration of the discharge down to 10 ns with an instantaneous power in excess of 1 MW/m2. Optical emission spectrum show changes in the electron energy distribution function which is consistent with kinetic analysis based on...
