Abstract
A cold atmospheric-pressure plasma jet device (3) has at least one capillary tube (20) with at least one noble-gas feed inlet (22), a plasma generation zone (24), and at least one plasma outlet (26). The capillary tube has, downstream of the plasma generation zone and upstream of a distal part of the capillary tube, a portion (60) having an enlarged cross-section, preferably the portion having the enlarged cross-section having a width-to-height ratio between 0.1 and 1000, the width corresponding to the maximum inner diameter of the portion having the enlarged cross-section.
Claims12
