AURA-WAVE (Sairem)

AURA-WAVE is an Electron Cyclotron Resonance (ECR) coaxial plasma source. It has been designed to be self-adapted once the plasma ignited. A magnetic field combined to the electromagnetic wave allows the creation of plasma at low pressure due to Electron Cyclotron Resonance. AURA-WAVE microwave plasma source has been designed to sustain microwave plasma over several decades of pressure, i.e. from 10⁻⁴ mbar to a few 10⁻² mbar and from a few watts depending on the gas.

Ion Wind DBD

The Ion Wind DBD uses a flat plasma electrode to create a surface dielectric barrier discharge (DBD) in the room air flowing over it. An additional “extraction” electrode is arranged in parallel to form a rectangular ventilation duct. The extraction electrode is charged, so that an additional unipolar electric field through the ventilation duct is created. This drags the ions of one polarity (either positive or negative) generated by the surface DBD in the direction of the extraction electrode.

Venturi-DBD (VDBD)

The gas pressure is an effective parameter to control plasma-chemical reactions, but its adjustment often requires substantial effort. In the Venturi-DBD (VDBD), the pressure can be set to any value between 100 mbar and 1000 mbar reliably and reproducibly. Using a Venturi pump for vacuum generation ensures that the system is affordable and almost maintenance-free. With air as process gas, the output gas composition can seamlessly be adjusted from a strongly ozone-dominated regime to a nitrogen oxides-only-regime including nitric oxide.


The Plasmaskop plasma source is designed to be inserted into the working channel of a conventional endoscope. It has a tube-like character, is flexible, very thin and generates a biologically active jet plasma at the gas outlet. The device consists of an inner plastic tube, a ceramic nozzle, an outer plastic tube and a metal wire. The inner plastic tube is plugged upon the thin end of the ceramic nozzle. In order to provide high voltage at the end of the tube and at the same time maintain tube flexibility the metal wire is coiled around the inner tube.
