| 内容記述 | During an Earth eclipse of the SCATHA spacecraft, the spacecraft charged to potentials greater than 1KV for about 30 minutes with extended excursions greater than 4KV. The composition of the hot plasma was obtained in the 0.1 to 32 keV energy range with an ion mass spectrometer aboard the spacecraft. Prior to the onset of the charging event, H(+) was the principal plasma ion, and during the event O(+) was the principal ion. The composition was energy dependent and varied significantly on a time scale of 4 minutes. An assumption that the ion flux was all H(+) led to computed number densities that were in error by more than a factor of two for several time intervals during the event. |
