The proposed drive system allows for the generation of up to four 4 high-quality radiographic pulses along one line-of-sight, having arbitrary pulse spacing 500 ns. This concept uses a four-pulse drive system to drive both a 16-MeV ensemble of 250-kV, 4-kA induction cells and a four-pulse, 4-MeV injector. The key to this approach lies in the method used to combine four pulses from different generators in a manner that does not compromise the voltage flatness requirement of - 1. The induction cells use core material for only a single pulse and use a simple reverse bias circuit to reset the cores between pulses. A dual double-pulse format has been identified which provides a sequence of two pulses along one line-of-sight within a 2-microsec window followed by a similar sequence of two pulses along the same line-of- sight within a second 2-microsec window. The 2-microsec windows can be separated by arbitrary time intervals of 2-to10-microseconds.
