Scientific paper

The Solar Wind Around Pluto (SWAP) plasma instrument on New Horizons (NH) made in situ measurements of the ~35 eV/Q to 7.5 keV/Q ions in Jupiter’s magnetosphere from DOY 56 to DOY 172, 2007, including first ever observations of the ~150 to 2550 RJ magnetotail region. Initial analysis of the SWAP magnetotail observations revealed plasma distributions that were highly variable in energy and flux, showing both sharp and smooth variations between different ion populations [McComas et al. 2007]. Here, we present a study that uses a plasma composition analysis technique developed for SWAP [Ebert et al. 2010] to statistically distinguish between light (mass ≤ He) and heavy (mass > He) ion counts in the SWAP magnetotail observations. Our analysis indicates that the < ~ 1 keV/Q magnetotail plasma is composed primarily of light ions, including the two most intense ion bursts in the tail at ~800 RJ and 1300 RJ, respectively. Heavy ions were identified at energies > 1 keV/Q, energies where this technique is less effective. We compare our results on plasma composition with measurements from the Pluto Energetic Particle Spectrometer Science Instrument (PEPSSI) on NH. We find many of the SWAP heavy ion intervals to correlate with sulfur-rich, velocity dispersive particle bursts identified in the PEPSSI energetic particle observations [Hill et al. 2009], suggesting that the heavy ion intervals are low energy (<7.5 keV/Q) extensions of these dispersion events.
