Abstract
A simple method is presented for determining the beam electron energy E e within the 4 – 18 MeV range. The method is based on a linear dependence between E e and the distance the plane of the electron beam (EB) input into a sample of polymethylmethacrylate (PMMA) from the remote boundary of the visible traces of internal electric discharge. It is shown that the EB current density profile may be determined by a set of beam tracks in the form of porous mass produced in the irradiated sites of the PMMA plate due to radiation gas evolution.
