Abstract:In this research, we study how the thickness of a 3D-printed collimator affects highenergy electron scattering. As part of this work, an ABS plastic absorber was produced by fused deposition modeling. Dose distributions at the boundary of the plastic absorber were experimentally observed for 6, 12, and 20 MeV electron beams. For plastic absorber thicknesses of up to 3 cm, dose "hot spots" are observed at the boundary between the primary beam and the beam that has passed through the absorber for 12 and 20 MeV e… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
