Calculation of absorbed dose of low-energy electron beam by an approximate method

In this work, we present a simple method to calculate absorbed doses of low-energy electron beams together with an experimental procedure for calibrating the accelerator under certain work conditions. The semi-empirical method is useful for a rapid estimation of depth-dose curve of electron beams, which uses an adjustable parameter factor determined by the least-squares fit from experimental values. Our approach is tested in electron processes on different materials, obtaining reasonable agreement. (C) 2002 Elsevier Science Ltd. All rights reserved.
