Classification: CPC H | IPC H

Claim 0:
1. A plasma source, comprising:
a first hollow electrode and a second hollow electrode separated by a gap of a constant width and a dielectric barrier;
wherein, providing a plasma-forming gas having a first breakdown voltage and a non plasma-forming gas having a second breakdown voltage larger than the first breakdown voltage, the plasma source is configured to selectively produce a plasma in either one of a first configuration and a second configuration;
wherein:
i) in the first configuration:
the plasma-forming gas flows in said gap while the non plasma-forming gas flows within said first hollow electrode; and
ii) in the second configuration, the plasma-forming gas flows within said first hollow electrode and the non plasma-forming gas flows within said gap.
