- Abstract
Pulsed power technology is the key technologies of the future of national defense, while the intense electron beam source development is the high-power microwave bottlenecks. Based on previous experimental, a pseudospark discharge is a viable possibility in this respect, a small-scaled and intense PS electron beam source was conceived to drive a high energy microwave tubes. The electrons emission is the first step of Pseudospark discharge plasmas breakdown, due to high-field emission. Based on filed emission mechanism, a cathode spot heat conduction model of Pseudospark discharge is set up to deduce the microscopic transport characteristics of initial plasmas by mathematics model building method and thermodynamics motion equations. The microscopic transport characteristics of initial plasmas are embodied mainly in the breakdown phase of discharge. So, the breakdown time(trigger delay) of Pseudospark is calculated from the heat conduction model. This research of plasmas discharge microscopic transport characteristics in order to lay the theoretical foundation for the optimize and improve Pseudospark device design.
