“…At present, using high-power electron beams, the features of destruction of metals [1,2], polymers [3,4], and composite materials [5] have been studied in sufficient detail. However, the behavior of polymer gels, using the example of igdantin, showed an interesting feature -under a powerful electron beam impact with an energy of more than 1 MeV, the decisive role in their destruction is played not by shock-wave, but by radiation-thermal processes [6]. In this regard, the study of such materials is of particular interest from the point of view of searching for threshold values of the input energy for triggering radiation-thermal processes.…”

This paper presents the results of a study of the impact of a high-current electron beam of the Kalmar accelerator with a cutoff electron energy of up to 350 keV on igdantine and low molecular weight nitrile butadiene rubber SKN-18-KTR. The materials are similar in mechanical and physical properties, but differ in chemical structure. It has been shown that, at a beam energy of less than 600 J, the destruction of igdantin begins to a depth significantly exceeding the electron range, while nitrile rubber withstands a load of more than 700 J without significant damage. It is demonstrated that the dynamics of plasma expansion from the surface of igdantin regularly demonstrates specific.
