Quantifying Nuclear Reactions in Metal Hydrides at Low Energies
POSTER
Abstract
We present deuterium-deuterium fusion rate measurements at low kinetic energies (<15 keV) in metal hydride foils, specifically Palladium- and Titanium-based targets. Fusion reactions are induced between deuterium atoms in the foils and deuterium ions from a sputter gun (200 μA, <15 keV). Two loading methods are investigated: electrochemical and direct ion beam loading. Preliminary results show differences in fusion reaction rates between these two modes. Fusion products are detected using a surface barrier detector and neutrons are measured with an EJ-309 detector. Future work will incorporate plasmonic structures to explore potential enhancements in fusion rates.
