Trigger reliability of xenon flashlamps

Abstract
The probability that a trigger pulse will successfully allow a driver circuit to discharge its energy through a xenon flashlamp is discussed. Based on a classical description of trigger spark formation and propagation statistics, the misflash probability, Pm, is described in terms of the ionization rate in the flash-lamp, β; the trigger pulsewidth, te; and the normalized trigger pulse overvoltage (Vs- Vst)/Vdc. This model was experimentally validated for series and parallel trigger circuits over a broad range of trigger pulse voltages, Vs, and pulseforming network voltages, VB.
