摘要：

This paper summarizes the structural design and experimental study of UV pre-ionizing for multi-gap gas switch. The structures of needle UV pre-ionizing and hole UV pre-ionizing are designed. Static properties of switches with three trigger structures are obtained. There is no evident change of static field in switches and the change of self-breakdown voltage is under 3% with UV pre-ionizing. The jitter of UV pre-ionizing switches is about 20% less than that of the switch without UV pre-ionizing. The needle UV pre-ionizing method can lower the trigger voltage by 10 kV, and the hole UV one by 5 kV. For needle UV pre-ionizing, the UV intensity with different trigger voltages, gas pressures and distance of UV gap are measured. The optimum distance of UV gap is experimentally determined as 1.5 mm to 3.0 mm and the jitter of switch is under 2.0 ns.
