Ablation from multiwire arrays made of fusible metals

This work is devoted to consideration of the process of plasma production determined by the local Ohmic heating inside remnants of initial explosion of wires. An approximate formula for quasi-stationary rate of ablation is obtained that contains total electric current through the array, its diameter, number of wires in the array and diameter of cylindrical clouds of the cold remnants. Besides them this estimation contains certain characteristics of metal the wires are made of.
