A triggered spark gap for discharging spark chambers [PDF]

open access: yesNuclear Instruments and Methods, 1967
Abstract A compact, simple, internally triggered spark gap for discharging spark chambers is described. The pulse on the spark chamber provides the trigger spark by charging a capacitor formed by the trigger electrode, one of the two main electrodes, and an alumina dielectric until a surface breakdown occurs across the dielectric.
