Plasma as a cross-sectional technology in many industry branches, but also in research laboratories, is an indispensable tool in surface treatment. Plasma technology is used everywhere where quality, productivity, environmental sustainability, precision and flexibility is important. Surfaces are cleaned, activated and decontaminated at atmospheric pressure with the handy kINPen® IND. The device is particularly used for surface treatment of temperature-sensitive materials as, for instance, plastics.
The invention relates to a device for generating a cold, HF-excited plasma under atmospheric pressure conditions, comprising a metal housing functioning as a grounded electrode in the region of the emergent plasma, wherein an HF generator, an HF resonance coil having a closed ferrite core suitable for the high frequency, an insulating body acting as a gas nozzle, and a high-voltage electrode mounted in the insulating body are disposed in such a manner that they are permeated or circulated around by process gas.
A plasma tool for generating a cold plasma beam (10) is described. The plasma tool is defined by the fact that it has a plasma nozzle, in particular a plasma nozzle which is dimensioned for operation by hand, wherein at least the coil (6) of the adaptation network is integrated into the plasma nozzle, for operation with a high frequency generator in addition to the capacitor C2, while the capacitor C1 can be arranged in the generator itself or in its vicinity.
