Formation and dynamics of plasma layers formed on the foil surface under the action of a high-current pulse

One looked into the possibility to use a thin metal foil to make replaceable vacuum supporting lines with a magnetic insulation in terms of the concept of a fusion reactor based on the high-voltage high-current electromagnetic oscillators. To determine the foil explosion threshold when exposed to heating by pulse current and to determine the parameters of a plasma layer produced at the surface one performed the experiments using the Angara-5 facility and carried out the numerical calculations. On the basis of the calculations one specified the threshold of plasma occurrence at the surface and compared it with the experimental data. One derived dependences of the plasma layer parameters on the linear density of current
