The first studies of two types of structural materials of plasma systems under the in-fluence of a high-current electron beam at the Calamary installation were carried out. Beam exposure parameters close to the emergency modes of some types of plasma systems are selected.

When a high-current relativistic electron beam interacts with the polymer surface, plasma forms. The results of a plasma dynamics study in vacuum diode using laser shadow photography, including the effect of atypically rapid propagation of the glow, are presented. Experiments were carried out on the high current generator «Calamary». Series of the experiments to study the plasma propagation along the diode axis and in the transverse direction in different cross sections were performed. The results were discussed and possible ways to continue research were considered.
