The measurement of plasma density at the periphery of Z-pinch on Angara-5-1 facility

In the physics of the wire array implosion the amount of the substance left on the periphery of the initial wire array at the moment of final liner implosion is an essential factor. Estimates show that plasma with a small mass fraction (a few percent of the initial wire array mass) may shunt an appreciable current fraction which can result in changing output characteristics of implosion. The given paper reports the investigation into the plasma density distribution on the periphery of the initial wire array near the moment of final implosion.
