Investigation of beam uniformity in industrial electron accelerator

In this paper the performances of the industrial electron beams processing, with 5 and 10 MeV energies, has been investigated by measuring two-dimensi onal 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 t hat were converted by interaction of electron with a high power X-ray targe t. The experiments have been performed using several types of film dosimete rs such as PVB, CTA and FWT. These dosimeters are used for beam profile mea surement and precise dose evaluation. The obtained results clearly show tha t the electron beam emerging out from scanning hom has a good uniformity al ong the electron beam profile. (C) 2001 Elsevier Science Ltd. All rights re served.
