High-Power Triggered Gas Switches

摘要

Examples of ultrawide band sources using self-closing spark-gap type of gas switches are the H-series systems at Air Force Research Laboratory. There are several reasons to build triggered versions of the basic high-voltage spark gap. They include synchronization with an external event, timed-array antenna for steering directed energy systems etc. Phase I includes a systematic formulization of a short pulse testbed facility. The fabrication and delivery of the facility is proposed for a Phase II effort. The designed facility is modular and capable of studying different types of electrical and laser triggering, gas mixes, electrode geometries, etc. The conceptual layouts and electrical field calculations have been completed in the critical stressed regions of the system. The 2-D transmission line code was used to model the circuit and preliminary runs were made. The contractor intends to develop this further in the Phase II effort and predict waveshapes.
