Abstract
An apparatus and methods to increase and direct the spatial volume of atmospheric pressure plasma jets. One or more additional gas flows is introduced to intersect the plasma jet. As the plasma jet interacts with these additional gas flows, the direction of propagation of the plasma jet is altered, the plasma expands into the volume defined by the additional gas flow, and the volume and effective surface area of the plasma jet increases accordingly, while the power increase needed to drive the increase in plasma volume scales sub-linearly with the increase in volume.
