Abstract:
1. A system for generating a plasma, comprising: a helicon plasma source and an electron cyclotron resonance (ECR) plasma source structured and arranged together to generate a plasma in a tube, wherein the ECR plasma source comprises: a microwave power source; a circulator; a load; a stub tuner; and a horn and wherein the microwave power source comprises a 2.45 GHz magnetron with 2000 W peak power; the circulator and the load are structured and arranged to protect the microwave power source from reflected microwaves; the stub tuner is structured and arranged to match an impedance of the microwave power source to the plasma inside the tube; and the horn is structured and arranged to shape and direct microwave power generated by the microwave power source into an interior cavity of the tube.
