Abstract
This report is devoted to the structured Z-pinch with long time implosion. Experiments were carried out on GIT 12 inductive storage. In the experiment with an outer gas puff and an inner wire array, we have been able to attain efficient switching of the current on a level of 2.1 MA into the wire array. The total implosion time was 300 ns, while the time of implosion of the wire array was not over 100 ns. The final velocity of the wire array was 5·107 cm/s. The switching occurs owing to the anomalous resistance appearing in the outer gas puff when heavy gases (krypton and xenon) with small masses are used for the gas puff material.
