Abstract:
1. A plasma discharge device comprising: A. Two discharge chambers, each containing ionisable gas mixtures, stacked vertically on top of each other, B. A central electrode disposed adjacent to or protruding in the discharge region, C. Electrical means of ionizing the gas, said means being electrically coupled to including a power supply, said power supply comprising a battery, an oscillator and flyback transformer, D. Means for increasing the capacitance in specific regions of the discharge chambers in the form of circular tracks depressed into the dielectric structural walls, E. Means for converging the luminous discharge at a specific point including electrode assemblies fitted into the tracks, said electrodes being electrically biased out of phase with respect to central electrode, F. Means for moving the grounding electrode assemblies along their respective tracks including a mechanical mechanism.
