“…An X-ray pinhole camera was used to determine the size of the region of interaction between the beam and the target. Also, the plasma dynamics in the diode gap was studied by the method of laser shadow photography with streakcamera registration [9]. Image synchronization was implemented by registering an image of an LED triggered by a pulse from a current-measuring shunt.…”

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.

“…Laser shadow chronogram was used to visualize the dynamics of the passage of shock waves in transparent materials [1] and to record the plasma dynamics in the diode gap of the generator [2]. The method is based on analysis of the shadow streak image formed by probe laser radiation that passes through a sample.…”

We studied the impact of a powerful relativistic electron beam on polymer targets at energy density up to 1 kJ/cm2. Experiments were carried out on high current electron accelerator “Kalmar” at beam current up to 45 kA and electron energy up to 300 keV. Laser shadow streak image was used to visualize the dynamics of shock waves in transparent materials. Three-dimensional numerical simulation of gasdynamic phenomena in the diode gap and elastoplastic phenomena that depend on them in the target material was performed using MARPLE3D multiphysics software package. The new technique was designed for end-to-end modeling including heating and evaporation of the target under the action of the electron beam and nonlinear wave processes leading to internal fractures and spalling phenomena in the target material. We use wide-range equation of state for the description of the liquid and solid phases of matter at low temperatures. Appropriate modeling of this complex problem is based on high resolution numerical methods as well as on high performance computing. The implemented computer models are verified by experimental data. The developed software can be used for numerical stress-strain analysis of various structural units loaded by strong pulsed forces and/or energy fluxes.
