dc.description.abstract From 1995 to 2003, the Galileo Heavy Ion Counter (HIC) monitored the high energy (~6 to >200 MeV/nuc), heavy ion (6C to 28Ni) fluxes at Jupiter and returned data for all but 2 of the 35 orbits of the Jupiter system. HIC was based on a re-engineered Voyager Cosmic Ray System instrument and was flown in part to gain a better understanding of the heavy ion radiation environment at Jupiter than that given by the brief flyby missions of Pioneer and Voyager. These spacecraft found oxygen and sulfur to be the primary constituents in the heavy ion environment at Jupiter—HIC adds carbon, believed to be of solar origin, to the list. While the sulfur is primarily Io-genic, the oxygen is from mixed sources being either of solar origin or from sputtering off the icy moons of Jupiter. After a brief review of the instrument and its measurements, a quantitative model of the average spectra of these heavy ions in terms of radial distance and energy is presented. The data, averaged over pitch angle, are from the so-called Galileo HIC “real time event” data and cover a wide range of radial distances and local times. The model is intended to provide a reference for the background energetic carbon, oxygen, and sulfur environments en_US
