Experimental research of extended lifetime trigatron with new trigger electrode

The lifetime of conventional trigatron is limited by the erosion of the trigger electrode. An extended lifetime trigatron was designed with three new types of trigger electrode based on the analysis of trigger mechanism. The experimental results indicate that the performances of the new trigatron are as high as the conventional trigatron. The minimum delay time of the new trigatron is 77 ns and the jitter is 2.5 ns.
