Small-gap gas switch for high-voltage pulse generator

The invention discloses a small-gap gas switch for a high-voltage pulse generator. The small-gap gas switch comprises a switch positive electrode and a switch negative electrode, wherein the switch positive electrode and the switch negative electrode protrude towards opposite sides in ellipse shapes, a switch trigger electrode is arranged between the switch positive electrode and the switch negative electrode, two ends of the switch trigger electrode are in ellipse shapes and are sunken towards centers, gaps are formed among the two ends of the switch trigger electrode, the switch positive electrode and the switch negative electrode, the gaps change with sunken curves of two ends of the switch trigger electrode and are gradually reduced towards a direction near to the center of the switchtrigger electrode. The gas switch which is fast in switch conduction and having relatively low delay jittering is achieved. 本发明公开了种用于高压脉冲发生器的小间隙气体开关，包括开关正电极、开关负电极，所述开关正电极与开关负电极均向对侧呈椭圆状突起且在两者之间设置有开关触发极，所述开关触发极的两端呈椭圆状向中心凹陷且分别与开
