On the Multi-Section Quenched Gap

The authors consider the relation between the breakdown voltage of a series of quenched gap sections and that of a single section. Because of electric flux leakage from each plate to nearby plates and neighboring conductors, the relation of direct proportionality does not hold. The breakdown voltage of a number of gaps of given length can not be made to exceed a limiting value, given in the paper. The limiting value in question is shown graphically for various values of flux leakage and breakdown voltage of gap. When spark circuit and antenna circuit are coupled, magnetically, the available limiting breakdown voltage is twice that for direct coupling with one side of the high voltage transformer grounded.
