Abstract
Concentrations of H+, He+, and O+ ions have been measured from an initial perigee height of ∼300 km to an apogee of ∼23 RE by the light ion mass spectrometer aboard OGO 5. The instrument has a sensitivity of less than 1 ion/cm3 and a range of 8 orders of magnitude. With these capabilities the instrument was able to measure ion concentrations from within the plasmasphere through the plasmapause and the ‘trough’ region of the outer magnetosphere. In this paper we are concerned with the position and density profile of the plasmapause which is generally located in the region ∼3≼L∼6.
