| 内容記述 | Simultaneous observations of H(+) and O(+) ions from the suprathermal ion mass spectrometer on Akebono and the energetic ion composition spectrometer on Dynamics Explorer 1 are reported. These observations were performed simultaneously above and below regions of ion acceleration on auroral and polar cap magnetic field lines. The evening auroral zonal data directly confirm the existence of an ionospheric preenergization mechanism for oxygen ions. The preenergized oxygen ions have characteristic energies of the order of 10 eV and are transported to altitudes of several thousand kilometers where they acquire significant additional energy. The data indicate that the creation (energization) and transport of streams of upflowing ions in the polar cap is more complex than previously anticipated. |
