Abstract
Abstract An apparatus for generating a short duration higher peak voltage pulse from a basic lower pulse voltage of longer duration. A series of spark gaps are arranged such that the total voltage from the basic long duration pulse is applied to each gap in succession. A delay line with a fixed delay which is equal to the total breakdown time of all the other gaps is connected across each spark gap.

Total Claims: 3
Claim 1
Independent Claim
161 words
A spark gap pulse generator apparatus for providing a short pulse width higher peak voltage pulse form a longer pulse width lower peak voltage pulse comprises in combination: A pulse generator for providing input pulses; A plurality of spark gaps connected in series with said pulse generator to receive said input pulses; A plurality of delay lines arranged in parallel with respect to said pulse generator, one end of said plurality of delay lines being connected respectively between said plurality of spark gaps to delay said input pulse prior to application to the next successive spark gap, the other end of said delay line having resistors to connect them to each other respectively and to said pulse generators; A first terminal connected to an input delay line-resistor pair, said first terminal providing the high-voltage output for said pulse generator; and, A second terminal connected to an output delay line-resistor pair, said second terminal providing the low-voltage output for said pulse generator.
