Title:     Development and Implications of ISOL Target-Materials with High-Carbon content for Short-Lived Radioactive Isotope Beam Production

Abstract: ARIEL is under construction to expand TRIUMF's scientific capabilities with the development of two additional ISOL target systems for TRIUMF. This expansion entails a greater demand for target material, promoting the research and development of new targets tailored for enhanced isotope release and improved resilience under high-power beam irradiation. This seminar presents the research and development towards reducing several limitations of the current ISOL-target paradigm.
A new method for synthesizing UCx targets has been developed. The reduction in the production time of the UCx targets complies with ARIEL's future target material demand, and it has relieved personnel and equipment, allowing the development of a novel graphite-composite target. Both targets have been characterized and submitted online for isotope delivery to experiments. Their performance has been studied and related to microstructure and thermal properties. Furthermore, analytical and a finite element models have been developed to predict their temperature during operation. Moreover, to further improve the performance of the targets, the implications of operating target materials with high carbon content have been investigated. Also, strategies are proposed for further learning about carbon penetration, the resulting target ovens' corrosion, and its prevention.
