Study of electrode parameters evolution during power transmission by submicrosecond current pulse with linear density above 1 MA/cm via magnetically insulated transmission lines
During transmitting the electrical energy in the current pulse with high linear density (1-3 MA/cm) the electrodes are exposed to extreme stresses caused by the heating of the electrode material and its compression of magnetic field. Numerical data on the dynamics of the spatial distribution of temperature, pressure and density in the cylindrical electrodes made of aluminum, tungsten and stainless steel, during the current pulse and after its completion are presented.
