Abstract:

Previous investigators have demonstrated the feasibility of using an ionizing electron beam to control the conductivity of a gaseous, volume-discharge switch. We have considered the possibility of using such switches repetitively at high power levels up to 10 to the 10th power W, with switch opening and closing times as short as several nanoseconds. An analysis of the relevent gas chemistry has indicated that these requirements can best be met by using a non-electronegative base gas diluted with a small percentage of an electronegative gas. Detailed chemistry simulations, using the non-electronegative gas N2 and the electronegative gas Osub2, have been performed and will be presented to support this analysis. Also discussed will be the limitations imposed by switch heating and gas breakdown.
