Apparatus and method for tunes unsteady flow purging of high pulse rate spark gaps
This patent describes a spark gap switch apparatus capable of operating at a high pulse rate. It comprises: an insulated housing; a pair of spaced apart electrodes each having one end thereof within a first bore formed in the housing and defining a spark gap therebetween; pressure wave reflector means in the first bore in the housing and spaced from the spark gap; and a second enlarged bore contiguous with the first bore and spaced from the opposite side of the spark gap from the wave reflector means; whereby pressure waves generated during discharge of a spark across the spark gap will reflect off the reflector means and back from the enlarged bore to the spark gap to clear from the spark gap hot gas residues generated during the discharge and reestablish the initial pressure and density of purge gas within the spark gap.
