Comparative study of the response of plastic materials to the high-current electron beam of the Кalmar facility impact

Abstract

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.
