of obtaining an impulse excitation of the secon-dary is to insert so much resistance in the primary that itscuiTent falls away aperiodically (see Sec. 116, p. 257). This hashowever, the disadvantage that considerable energy is lost inthe primary due to the heating of the rather large resistanceof… … A more satisfactory arrangement is the quenched gap. Bydividing the spark gap in the primary into a number of shortgaps in series, the cooling effect of the relatively large amountof metal is available for carrying away the heat of the sparkdischarge. This is found to be sufficient, in the case of…
