Description
On the 15th of June 2006, the PAMELA satellite-borne experiment was
launched from the Baikonur cosmodrome and it has been collecting data
since July 2006. The apparatus comprises a time-of-flight system, a
silicon-microstrip magnetic spectrometer, a silicon-tungsten
electromagnetic calorimeter, an anticoincidence system, a shower tail
counter scintillator and a neutron detector. The combination of these
devices 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.
Moreover, PAMELA is investigating phenomena connected with solar
and earth physics.
