Investigation of beam uniformity in industrial electron accelerator

摘要

In this paper the performances of the industrial electron beams processing, with 5 and 10 MeV energies, has been investigated by measuring two-dimensional dose distribution in electron beam profile. Large volume of absorbing materials with densities 0.5 and I g/cm(3), which are wood and polyethylene, respectively, are used as the irradiated materials. On the other hand the mentioned measurement are also performed for X-ray (Bremsstrahlung) beam that were converted by interaction of electron with a high power X-ray target. The experiments have been performed using several types of film dosimeters such as PVB, CTA and FWT. These dosimeters are used for beam profile measurement and precise dose evaluation. The obtained results clearly show that the electron beam emerging out from scanning hom has a good uniformity along the electron beam profile. (C) 2001 Elsevier Science Ltd. All rights reserved.
