Overview

Non-equilibrium atmospheric pressure plasma jets (APPJs) are of intense interest in current low-temperature plasma research because of their immense potential for material processing and biomedical applications. Depending on the jet configuration and the electrical excitation, plasma characteristics including heat, charged particle, electric field, and chemically active species may differ significantly. Other important parameters of importance in these studies are the kind of utilized working gas and gas flow rate. This book presents the electrical characterization of DBD-based APPJs for three electrode arrangements: ring electrode, pin electrode and floating helix electrode configurations.The analysis presented here will serve to help in establishing an optimum range of operation for a cold plasma jet without arcing and without any physical damage to the electrodes. Furthermore, the experimental results provided in the book establish the significance of the type of working gas on the power consumption and on the jet length obtained. These developed cold DBD-based APPJs of larger lengths may be useful for diverse biological applications and surface treatments.
