【 摘 要 】

We study the evolution of tube material during the power current pulse is passing. Modelling this process, we need the time dependence of current, restored according to the time dependence of the electric field intensity, measured at the inner tube surface. For this purpose, the inverse problem was solved; the data obtained were used in the MHD-simulation.
