Abstract
A particular gas mixture (90% N.sub.2 +10% Xe) in a triggerable spark gap discharger is disclosed which allows the spark gap to be triggered with a low main-gap voltage over a much wider range of trigger voltages (e.g., 16-30 or more kV), than with nitrogen (e.g., 19-22 kV) or other commonly used gases and mixtures. The improvement is important where triggerable spark gaps are used in protective circuits.
