Abstract:

This work describes the design of a sequencer that combines electrical pulses from multiple Marx generators for use in flash X-radiography systems. The design isolates high-voltage conduction pathways by using field emission effect-based diodes. Combination of two pulses was demonstrated with millisecond temporal separation; however, the method is expandable to an infinite number of pulses. This work also explores influences leading to the millisecond temporal separation. Design modifications are suggested that have the potential to significantly reduce the temporal separation, which are mostly related to controlling the plasma within the diode gap.
