TRIGGERABLE SPARK GAP, SWITCHING CIRCUIT HAVING A TRIGGERABLE SPARK GAP, AND PROCESS FOR MANUFACTURING A TRIGGERABLE SPARK GAP

摘要

A triggerable spark gap (TFS) having a longer service life is disclosed. The spark gap includes a counter electrode (GE) having two phases. Material (M2) of which the second phase is made has a lower electron discharge energy than material (M1) of which the first phase is made.
