Abstract

A triggered vacuum switch (TVS) shows good performance when used in pulsed power systems. The time delay and lifetime are the important features of the TVS. We carry out several experiments to measure and analyze the time delay and lifetime characteristics of TVS with a multirod system. The results show that the time delay is strongly influenced by the polarity effect. The lifetime experiments are repeated for 1000 shots under two different operational modes. After repeated 1000-shot experiments, the TVSs are not damaged. The results prove that the TVS with a multirod system can work under a long lifetime in excess of 1000 shots. After the first 200 shots, the trigger voltage maintains between 40 and 1000 V, and the rise time and collapse time are around 2.5 μs.
