Delay and jitter properties of SF6-N2 mixtures triggered by pulsed laser

This paper presents the triggering property of SF6-N2 mixtures triggered by a quadrupled Nd:YAG laser. The delay and jitter increased as the pressure and the percentage of SF6 in SF6-N2 mixtures increased. The working ratio followed the same rule. The delay, jitter and the working ratio decreased as the wavelength of laser decreased when t he mixing ratio, pressure and charging voltage kept constant. The delay and jitter of SF6-N2 mixtures decreased as the focus length decreased. The better mixing ratio of SF6-N2 mixtures used as switching media should be 5%～45%(SF6) if the dependence the dielectric strength and the delay, jitter on the percentage of SF6 in SF6-N2 mixtures is nonlinear.
