Cold plasma surface modifi cation 211

homogeneous atmospheric pressure discharges during the last two decades

has resulted in several reports in literature on plasma sources that combine

the techniques that we previously discussed in this section. In Section 7.4.5 ,

we will describe two general concepts that combine several techniques and

that are being extensively studied.

Plasma jet

For several applications it is bene cial to dispose of a plasma source for

remote treatment, and recently a lot of research effort has been done on

this. These generated plasmas are not spatially bound or con ned by the

electrodes, and are often called cold plasma jets. Other terms for plasma

jets randomly used are plasma plume, plasma needle and plasma pencil ...
