Hydrogen Loading System Development and Evaluation of Tritiated Substrates to Optimize Performance in Tritium Based Betavoltaics
Abstract
dc:description.abstract<p>State-of-the-art hydrogen loading system onto thin metallic films based on differential pressure in calibrated chambers has been developed for conditions pressures and temperatures up to 69 bar and 500°C, respectively. Experiments on hydrogen loading on to palladium films of thickness 50 and 250 nm were conducted at pressure ranging from 0.2 bar to 10 bar at temperature 310°C. For first time film hydrogen loading was carried out at 1 bar and at room temperature which temperature. Beta flux exiting surface of metal tritide films has been modeled with MC-SET (Monte Carlo Simulation of Electron Trajectories in solids). Surface beta flux simulations have been improved to account for density changes from tritium loading and decay. Simulation results indicate a 300 nm slab of MgT<sub>2</sub> has a surface flux three times higher than in ScT<sub>2</sub>, and six times higher than in TiT<sub>2</sub>. Commercial betavoltaic cells were tested at different temperature environment for their evaluation and characterization.</p>
