Plasma Composition

The Ulysses solar wind ion composition (SWICS) experiment provided important new data on the composition of the magnetospheric plasma, in particular information on the charge states of the various ions. These measurements provided new insights into the sources and "life history" of the Jovian plasma. Material from three sources, the solar wind, the planet itself and the volcanic satellite Io (Iogenic ions) can be traced by observing ions specific to each source. Large-scale mixing was observed to occur.
