Research of generation mechanism of plasma points in Z-pinch

Fast Z-pinches, formed at explosion of single thin wires by a powerful pulse of current, are by a subject of intensive experimental researches already more than twenty years /1,2/. The interest to these researches is associate with formation in pinching process of a plasma column, so-called “hot” points - high-temperature dense objects, intensively radiating in a soft x-ray region. The analysis of x-ray spectra shows, that electron temperature Te in “hot” points can reach about several keV, density ne ≥ 10²² cm⁻³. Such high specific parameters of plasma present doubtless interest for researches in the field of physics of high energy density, x-ray spectroscopy of multi charge ions.
