Abstract

We present a simulation configuration for the electron beam profile consistent with experiments on the linear accelerator UERL-10-15S2, focusing on determining electron energy and beam size. Two essential aspects of the electron beam described in the simulation configuration are the initial energy distribution and the initial beam size with the flux distribution. Notably, we introduce a new mathematical function by modifying the approximated Landau distribution. This new function offers a better fit than our previous mathematical function and, more importantly, accurately reflects the physical nature of the energy spectrum of electrons passing through a thin layer of matter. Using this configuration, we have simulated the irradiation of zeolite ETS-10 by the electron beam. This irradiated simulation was set up with various electron energy distributions, yielding results on the dose rate distribution (2D dose map) and the mean absolute percentage deviation of the absorbed dose rate within the irradiated titanosilicate. With the improvements in this paper, we have provided a solution to enhance the linear accelerator’s application in scientific research besides conventional industrial irradiation applications.
