Abstract

An apparatus is provided. The apparatus includes a plasma generation element physically coupled to a first main electrode. The plasma generation element includes at least a first open end and a second open end. Each open end defines a nozzle such that the first open end directs an ablative plasma to a second main electrode and the second open end directs the ablative plasma to a third main electrode.

Claims (24)

1. An apparatus comprising:

a plasma generation element physically coupled to a first main electrode, the plasma generation element comprising at least a first open end and a second open end, wherein each open end defines a nozzle such that the first open end directs an ablative plasma to a second main electrode and the second open end directs the ablative plasma to a third main electrode.

2. The apparatus of claim 1 , wherein the first main electrode is hollow, and wherein at least a portion of the plasma generation element is disposed within the first main electrode.

3. The apparatus of claim 1 , wherein the plasma generation element physically coupled to the first main electrode is disposed on the surface of the first main electrode.

4. The apparatus of claim 1 , wherein the plasma generation element is configured to generate ablative plasma at a pressure of about 100,000 to 5,000,000 pascals.

5. The apparatus of claim 1 , wherein the second and third main electrodes are separated from the first main electrode by a distance of about 50 to 200 millimeters (mm).

6. The apparatus of claim 1 , wherein the second and third main electrodes are arranged substantially equidistant from the first main electrode.

7. The apparatus of claim 1 , further comprising a plurality of gun electrodes comprising at least a first gun electrode and a second gun electrode, wherein the first gun electrode comprises a first end and the second gun electrode comprises a second end such that the first end and the second end extend into the plasma generation element and define a gap therebetween for formation of an arc.

8. The apparatus of claim 7 , wherein the plasma generation element is configured to generate ablative plasma in a region defined between the first and second open ends and the first and second ends.

9. The apparatus of claim 8 , wherein the volume of the region is about 0.5 to 5 cubic centimeters.

10. The apparatus of claim 7 , wherein the gap between the first and second ends is about 0.1 to 2 mm.

11. The apparatus of claim 1 , wherein at least one of the first open end or the second open end comprises a diameter of about 0.2 to 5 mm.

12. An arc elimination system comprising:

a plurality of main electrodes comprising a first main electrode, a second main electrode, and a third main electrode; and

an apparatus comprising:

a plasma generation element physically coupled to the first main electrode, the plasma generation element comprising at least a first open end and a second open end, wherein each open end defines a nozzle such that the first open end directs an ablative plasma to the second main electrode and the second open end directs the ablative plasma to the third main electrode.

13. The arc elimination system of claim 12 , wherein the first main electrode is hollow, and wherein at least a portion of the plasma generation element is disposed within the first main electrode.

14. The arc elimination system of claim 12 , wherein the plasma generation element is physically coupled to the first main electrode is disposed on the surface of the fist main electrode.

15. The arc elimination system of claim 12 , further comprising a housing, wherein the plurality of main electrodes and the apparatus are disposed in the housing.

16. The arc elimination system of claim 12 , further comprising a trigger circuit configured to generate an electrical pulse for triggering the plasma generation element.

17. The arc elimination system of claim 12 , wherein the second and third main electrodes are separated from the first main electrode by a distance of about 50 to 200 millimeters (mm).

18. The arc elimination system of claim 12 , wherein the apparatus further comprises a plurality of gun electrodes comprising at least a first gun electrode and a second gun electrode, wherein the first gun electrode comprises a first end and the second gun electrode comprises a second end such that the first end and the second end extend into the plasma generation element and define a gap therebetween for formation of an arc.

19. The arc elimination system of claim 18 , wherein the plasma generation element is configured to generate ablative plasma in a region defined between the first and second open ends and the first and second ends.

20. The arc elimination system of claim 14 , wherein at least one of the first open end or the second open end comprises a diameter of about 0.2 to 5 mm.
