New Measurement of the Cosmic-Ray Positron Fraction from 5 to 15 GeV
J. J. Beatty, A. Bhattacharyya, C. Bower +12
We present a new measurement of the cosmic-ray positron fraction at energies between 5 and 15 GeV with the balloon-borne HEAT-pbar instrument in the spring of 2000. The data presen…
A new measurement of the altitude dependence of the atmospheric muon intensity
J. J. Beatty, S. Coutu, S. A. Minnick +12
We present a new measurement of atmospheric muons made during an ascent of the High Energy Antimatter Telescope balloon experiment. The muon charge ratio mu+/mu- as a function of a…
Measurement of the Cosmic-Ray Antiproton to Proton Abundance Ratio between 4 and 50 GeV
A. S. Beach, J. J. Beatty, A. Bhattacharyya +13
We present a new measurement of the antiproton to proton abundance ratio, pbar/p, in the cosmic radiation. The HEAT-pbar instrument, a balloon borne magnet spectrometer with precis…
Cosmic-Ray Positrons: Are There Primary Sources?
Stephane Coutu, Steven W. Barwick, James J. Beatty +15
Cosmic rays at the Earth include a secondary component originating in collisions of primary particles with the diffuse interstellar gas. The secondary cosmic rays are relatively ra…
Measurements of the Cosmic-Ray Positron Fraction From 1 to 50 GeV
HEAT Collaboration, S. W. Barwick, E. Schneider +16
Two measurements of the cosmic-ray positron fraction as a function of energy have been made using the High Energy Antimatter Telescope (HEAT) balloon-borne instrument. The first fl…
