Experiments are reported on the implosion of argon double gas puffs in the GIT-12 current generator (Tfr = 0.25 μs, Im = 2.3 MA). The gas-puff medium was preionized by different methods. The experimental data provide evidence for a strong effect of the initial conditions for the formation of the current-carrying shell on the implosion process. Emphasis is given to a discussion of the following issues: the enhanced scatter in both the emission power and X-ray yield in the Ar K-lines, the existence of a large number of current filaments, the uncertainty in the process by which the generator current is redistributed among a progressively smaller number of current filaments, and the redistribution of the generator current between the inner and outer gas-puff shells.
