| 内容記述 | High resolution magnetic field, thermal plasma, and energetic particle data measured on the IMP 8 spacecraft are used to demonstrate that a thin plasma sheet with rapidly flowing plasma undergoes violent oscillatory motion that causes the entire thickness of the plasma sheet to pass over the spacecraft in times which are sometimes as short as 10 s. Ions with 50 and 290 keV energy are investigated since their gyroradii are comparable to the plasma sheet thickness. As the spacecraft moves from the plasma sheet into the lobe, the energetic particle intensities decrease, but the 290 keV ions are relatively more numerous than 50 keV ions on field lines located deeper in the lobe. |
