Plasma jets presented here are based on cylindrical dielectric barrier discharges. Multi jet arrays formed from bundles of 6 and 10 individual single jets are realized in very compact housings. Surface treatments of polymers to increase their adhesion are discussed and compared to results achieved by other types of plasmas. A second type of ap plasma jet sources is based on an integrated ceramic t...Show More
The propagation of an atmospheric pressure plasma jet (APPJ) is investigated by use of an intensified charge coupled device (ICCD) camera. It is shown that the APPJ is mainly an electrical phenomenon and not a flow related one. The jet does not consist of a voluminous plasma. Much more, the presented plasma source acts like a "plasma gun" blowing small "plasma bullets" out of its mouth. Furthermor...Show More
