Study of the time dependence of the plasma formation intensity at the current implosion of cylindrical wire and fiber arrays from different substances

Popis výsledku v původním jazyce

A characteristic feature of the implosion of multiwire arrays on powerful high-current electrophysical facilities (ZR, Angara-5-1, Julong-1 (PTS), MAGPIE, etc.) is the process of extended wire ablation. It is based on the fact that the substance of the wires is not converted into plasma instantly, but is supplied into the discharge relatively slowly at the rate (m) over dot(t) in about 70-80% of the rise time of the facility current. It is believed that the plasma is formed on the surface of the cores of the exploded wires due to the energy coming from the hot plasma corona surrounding the core of the wire in the form of the heat flux and emission. In this paper, we propose a new approach to determining the quantity (m) over dot(t) as the main quantitative characteristic of the process of the extended wire ablation in wire (or fiber) arrays.
