Abstract
The energy spectra of cosmic ray protons and helium above 2 TeV/nucleon have been measured on a series of balloon flights by the JACEE collaboration. Since the last report of results from JACEE flights 1-8, an additional 700 hours have been added to the data sample from three long duration Antarctic flights (JACEE 10, 12, and 13). We will summarize the proton/helium analysis to date for JACEE flights 1-12.
