Patent Number 9067273
B23K 10/00 (2013.01)
Disclosed is an atmospheric pressure plasma jet device for use in a variety of applications. The disclosed system can include a conduit tubing array that includes multiple individual tubes configured in a honeycomb structure. By altering the linear velocity of the system's gas source, the system can produce multiple non-thermal atmospheric plasma jets that can interact in such a way as to create a single plasma jet as opposed to multiple collimated plasma jets. The single jet formed by the interaction of the multiple conduits can exhibit an increased optical intensity and energy compared to either a plasma jet emitted from a single conduit or well-collimated plasma jets emitted from multiple conduits.
