Parameters of high-pressure megaampere discharge channel during its contraction
Abstract
Results of determination of the discharge channel parameters in iron plasma for a stage of its maximal contraction are presented. Amplitude of the discharge current was of 500-1500 kA, current rise rate of 5 × 1010 A/s, surrounding gas pressure of 5-7 MPa. Results of intensity measurements for own plasma soft x-ray radiation and registration of radius evolution of current channel of the discharge, received with the help of magnetic probe diagnostics, confirm a hypothesis about radiative character of the discharge contraction. The developed system of soft x-ray radiation registration gives the discharge channel temperature of 72-73 eV and allows to register changes of temperature in some electronvolts.
