Heavy ion measurement on LDEF.
A stack of CR-39 track detectors was exposed on the NASA satellite LDEF and recovered after almost 6 years in space.  The quick look analysis yielded heavy ion tracks on a background of low energy secondaries from proton interactions.  The detected heavy ions show a steep energy spectrum which indicates a radiation belt origin.
