Systems and methods for generating plasma are disclosed. A system for generating a plasma includes a helicon plasma source and an electron cyclotron resonance (ECR) plasma source structured and arranged together to generate a plasma in a tube.

Hybrid plasma source

A method and apparatus for producing a distributed plasma at atmospheric pressure. A distributed plasma can be produced at atmospheric pressure by using an inexpensive high frequency power source in communication with a waveguide having a plurality particularly configured couplers disposed therein. The plurality of particularly arranged couplers can be configured in the waveguide to enhance the electromagnetic field strength therein. The plurality of couplers have internal portions disposed inside the waveguide and spaced apart by a distance of &#xbd; wavelength of the high frequency power source and external portions disposed outside the waveguide and spaced apart by a predetermined distance which is calculated to cause the electromagnetic fields in the external portions of adjacent couplers to couple and thereby further enhance the strength of the electromagnetic field in the waveguide. Plasma can be formed in plasma areas defined by gaps between electrodes disposed on the external portions.
