Summary

Previous studies of upflowing ions indicate that ion beams acquire their energy by a process which results in the heavier ions gaining additional transverse energy. Data from S3-3 are presented which provide evidence that ion beams can be the result of a two step acceleration process in which ion conics formed at lower altitudes are then accelerated through a potential drop. These ion conics, generated in regions below such potential drops and presumably within upward current regions, are produced by a mechanism which provides more energy to heavier ions.
