【 摘 要 】

For the purposes of the experiments on heavy ions deceleration in ionized matter a plasma target based on a linear electric discharge in hydrogen has been designed. The two-dimensional hydrodynamic code was used for numeric simulation of the main stage of discharge. Estimated distribution of electron density and the degree of plasma ionization along the discharge tube axis of the target at the time of maximum discharge current corresponds to the experimental measurements of time dynamic of linear electron density and degree of plasma ionization in the target.
