The charge state of the anomalous component
Abstract
The Trapped Ions in Space (TRIS) experiment was flown in a 57 deg orbit at an average altitude of 254 km in October, 1984, aboard the Space Shuttle. The detector was a stack of Lexan and CR-39 plastic track detectors. The observed orbit-averaged oxygen flux greatly exceeds what is expected from galactic and solar cosmic rays; the observed carbon flux agrees with galactic and solar expectations. If the excess oxygen flux is attributed entirely to fully-ionized nuclei coming from outside the magnetosphere, the inferred exomagnetospheric flux exceeds contemporaneous upper limits on the oxygen flux at 1 AU. The excess flux is consistent, however, with a singly-ionized anomalous component.
