“…where γ ph is Townsend's second ionization coefficient due to the action of photons at the cathode, μ is the photon absorption coefficient [10] in the gas, g(z) is a geometry factor to account for the photons received at the cathode from the primary avalanche during its growth at distance z along the gap axis and d is the gap spacing [9].…”

This paper is concerned with the calculation of electrical breakdown voltage in uniform-field short gas-gaps at varying pressures. The oxygen is chosen being the main gas component in the atmospheric air, which poses the electronegativity character to the air. The calculation is based on the criterion of self-recurrence of single electron avalanche growing in the gap. This ensures sustenance of gas discharge for gap breakdown to occur. The calculated breakdown voltage and current-growth values agreed reasonably with those measured experimentally in oxygen at varying pressure values.
