A conceptual two-stage microthruster employing sublimed molecules as the propellant of the first stage and alpha particles as the propellant of the second stage is analyzed. Transient thermal analysis is developed as a tool to provide design information on material compositions, the numerical result suggests that the radioisotope heating of the nozzle wall could help flatten the subliming surface temperature.
