Streamer breakdown mechanism
WebThe Townsend quasi-homogeneous breakdown mechanism can be applied only for relatively low pressures and short gaps (pd 200 Torr · cm). 1. The spark breakdown at high pd and considerable overvoltage develops much faster than the time necessary for ions to cross the gap and provide the secondary emission. process fails. 2. Web9 Aug 2024 · Breakdown probability densities for streamer and Townsend mechanisms in air (1 bar) along with the deterministic thresholds. The approximation uses the approximation of equation ( 24 ). The value γ = 10 −2 for the Townsend threshold was chosen to approximate the experimentally observed Paschen curve for air.
