Double sided irradiation on homogenous products of different densities at an industrial EB accelerator of 2 MeV energy

摘要

An industrial type 2 MeV/20 kW electron beam accelerator is operational in India for development of applications and technology demonstration to the Indian industry in the field of polymer modifications and for processing of various other products. For routine monitoring of beam current during radiation processing of products at the facility, a current density measurement system was fabricated using high quality graphite material. Depth-dose distribution was experimentally measured in materials of different densities for optimizing suitable thickness for double sided irradiation under 2 MeV beam. The present paper describes the features of the current density measurement system and experiments for optimizing thickness suitable for double sided irradiation for materials of different densities.
