Precision studies of cosmic rays with PAMELA
2008 (English)In: 37th COSPAR Scientific Assembly, 2008, Vol. 37, 2377- p.Conference paper (Refereed)
The PAMELA satellite-borne apparatus was launched into an elliptical low earth orbit with an inclination of 70 degrees on June 15th 2006. The combination of a permanent magnet silicon strip spectrometer, and a silicon-tungsten imaging calorimeter allows precision studies of the charged cosmic radiation to be conducted over a wide energy range ( 100 MeV - 100's GeV) with high statistics. The primary scientific goal is the measurement of the antiproton and positron energy spectrum in order to search for exotic sources, such as dark matter particle annihilations. PAMELA is also searching for primordial antinuclei (anti-helium), and testing cosmic-ray propagation models through precise measurements of the antiparticle energy spectrum and precision studies of light nuclei and their isotopes. Concomitant goals include a study of solar physics and solar modulation during the 24th solar minimum by investigating low energy particles in the cosmic radiation; and a reconstruction of the cosmic ray electron energy spectrum up to several TeV thereby allowing a possible contribution from local sources to be studied. The status of the PAMELA experiment will be reviewed, and initial scientific results discussed.
