Claim 23:
24. A plasma-generating device, comprising:
a cathode including a tapered distal portion;
an anode disposed downstream from the cathode and being electrically insulated from the cathode, the anode defining an opening therethrough;
a plurality of intermediate electrodes disposed between the cathode and the anode, the plurality of intermediate electrodes electrically insulated from each other and from the anode and the cathode, each intermediate electrode from the plurality of intermediate electrodes defining an opening therethrough such that the openings in the plurality of intermediate electrodes and the anode collectively define a plasma channel for discharging a plasma flow, the plasma channel including:
a first portion having a first cross-sectional diameter; and
a second portion having a second cross-sectional diameter, the first cross-sectional diameter being at least four times the second cross-sectional diameter; and
an insulator sleeve extending along a surrounding a portion of the cathode.
