ABSTRACT:
A microhollow cathode discharge assembly capable of generating a low temperature, atmospheric pressure plasma micro jet is disclosed. The microhollow assembly has at two electrodes: an anode and a cathode separated by a dielectric. A microhollow gas passage is disposed through the three layers, preferably in a taper such that the area at the anode is larger than the area at the cathode. When a potential is placed across the electrodes and a gas is directed through the gas passage into the anode and out the cathode, along the tapered direction, then a low temperature micro plasma jet can be created at atmospheric pressure.
