Abstract

A new measurement of the cosmic-ray positron fraction at energies between 5 and 15 Gev was performed. The combined data from the three HEAT flights indicate a small positron flux of nonstandard origin above 5 GeV. A new version of the HEAT instrument, HEAT-polar was also designed to observe the high-energy cosmic-ray anti-proton flux. It is observed that a primary contribution to the positron intensity above a few GeV can still not be ruled out.
