Abstract:
1. A plasma system, comprising: a plasma device including an inner electrode and an outer electrode coaxially disposed around the inner electrode, wherein the inner electrode includes an end distal portion extending distally past a distal end of the outer electrode and an insulative layer that extends up to the distal end of the outer electrode and covers the inner electrode at least up to the end distal portion of the inner electrode such that the end distal portion of the inner electrode is un-insulated; an ionizable media source coupled to the plasma device and configured to supply ionizable media thereto; and a power source coupled to the inner and outer electrodes and configured to ignite the ionizable media at the plasma device to form a plasma effluent having an electron sheath layer about the end distal portion of the inner electrode.
