The ubiquity of sulfur ions within the Jovian magnetosphere has led to suggestions that the implantation of these ions into the surface of Europa may lead to the formation of SO₂. However, previous studies on the implantation of sulfur ions into H₂O ice (the dominant species on the Europan surface) have failed to detect SO₂ formation. Other studies concerned with similar implantations into CO₂ ice, which is also known to exist on Europa, have offered seemingly conflicting results. In this letter, we describe the results of a study on the implantation of 290 keV S⁺ ions into condensed CO₂ at 20 and 70 K. Our results demonstrate that SO₂ is observed after implantation at 20 K, but not at the Europa-relevant temperature of 70 K. We conclude that this process is likely not a reasonable mechanism for SO₂ formation on Europa, and that other mechanisms should be explored instead.
