The implantation of reactive charged species within low-temperature solids is relevant to astrochemistry and may lead to physico-chemical changes within the solid, such as the formation of new molecules which incorporate the projectile. We have performed the high-fluence (>1016 ions cm–2) implantation of S+ into CO, CO2 and H2O ices at 20 and 70 K. Our results show that implantation into CO and CO2 results in the formation of SO2 at 20 K, although no evidence of SO2 was observed at 70 K. Implantation into H2O yields H2SO4 hydrates. These results are applicable to Europa; one of the Galilean moons of Jupiter.
