In summary, the effort will improve City Labs’ tritium power source to provide long-term power for small space satellites. The stacking methodology for robust assembly of devices with multiple layers of metal hydride and semiconductor material will be enhanced in this project. The effort will also result in an adequate helium diffusion mechanism in the electronic package which will enable the use of higher amounts of tritium in the power source devices. City Labs is the only licensed manufacturer of betavoltaic power sources which carries a General License allowing distribution to anyone in the United States without requiring the recipient to possess a radiation license. The proposed tritium betavoltaic power source will meet the AF customers’ requirement for an ultra-small, temperature resilient, continuous 5-10 year power capability.
