Abstract:

The paper concerns the study of the ~5 MeV electron beam interaction with the thin layer experimental sample at the AREAL electron linear accelerator. The necessary exposure time and the irradiation effects parameters calculations have been performed using measured parameters of the beam and numerical simulations applying particle transport code FLUKA. Numerical simulations with FLUKA provide estimation of the absorbed dose - the main parameter that defines the amount of the radiation induced crystalline structure defects. Calculations have been conducted for the experimental study of the irradiation effects on the parameters of the ferromagnetic composition Ba75Sr25TiO3 - Barium-Strontium-Titanate (BST) thin film. The main goal reached is the calculation of the required exposure time taking into account beam intensity, energy, spatial and angular distributions and experimental sample geometrical shape, size, composition and disposition for obtaining intended value of the absorbed dose. Beam parameters used for numerical simulations have been obtained from beam diagnostic measurements.
