Ceramic surface flashover triggering of pseudospark switchs

In this paper, a new ceramic surface flashover trigger of pseudospark switch is presented for the first time. Experiments demonstrate that this trigger has long lifetime and the triggered pseudospark switch provides an excellent delay of 50~340ns and jitter of 15~40ns at the discharge voltage of 30~2kV. The emitted plasma electron density is high enough to trigger switches reliably at a low voltage of 600V．
