Abstract

Embodiments of the present disclosure relate to a spark gap device that includes a first electrode having a first surface and a second electrode having a second surface offset from and facing the first surface. The spark gap device also includes a light source configured to emit light toward at least the first surface such that photons emitted by the light source when the spark gap is operated are incident on the first surface and cause electron emission from the first surface. The light source includes a discharge probe having a third electrode sealed in a tube filled with an inert gas. The spark gap device may not include a radioactive component.
