Emerging Methods for Target Fabrication in Nuclear Science Measurements

The safe and economical preparation of robust targets of desired thicknesses and uniformity remains a challenge in nuclear science studies. Over the last few years, we implemented new methods for preparing targets at the University of Notre Dame. This program investigates solution combustion synthesis (SCS) processes between metal nitrates with organic compounds to ensure the production of targets. Combining SCS processes with spin-coating, spraying, and inkjet printing techniques enables the preparation of isotopically pure, robust, and uniform targets with tunable thicknesses.I will present recent achievements in preparing stable and radioactive targets and discuss the relationships between process conditions, structure, and morphology of the resulting targets. I will also highlight selected target tests with charged particles and neutron beams. Then, I will present the results of target characterization with an array of advanced methods and emphasize the relationships between the structure of targets and their stability.
