ABSTRACT:
A multiconcentric coaxial cable uses three or more concentric cables to supply power to a high voltage laser with reduced waveform degradation otherwise produced by stray capacitance and inductance. Each pair of concentric conductors is in itself a coaxial line and the radius of each conductor is selected such that the characteristic impedances of the two lines it forms with the adjacent conductors are equal. Each line is charged with a polarity opposite to the adjacent lines. Polarity inverting switches are connected across the lines charged to the polarity opposite to the desired output polarity at the end of the cable opposite from the load connection. The load is connected to the outermost cable conductor of the cable. When the switches are closed the polarity of the cable sections to which they are connected reverse and the sum of the voltages on all the cable sections is applied to the self-breaking gap causing it to close and connect the load. The sum of the impedances of the cable sections is designed to be equal to the load impedance and therefore the energy from the cable to the load is matched.
