Abstract
A spark source is disclosed having an analytical spark gap, a capacitor, a power supply for charging the capacitor, and an electronic switching tube connected in a series circuit between the capacitor and the spark gap. When the tube is rendered conductive by a triggering pulse or other signal, the capacitor is discharged through the spark gap and the switching tube, which carries the entire discharge current.
