The PAMELA experiment will be launched on-board a Resurs DK1 earth observation satellite in 2005. During the three year mission, the primary objective of PAMELA is to measure the flux of antiprotons (80 MeV - 190 GeV) and positrons (50 MeV - 270 GeV) in the cosmic radiation. The wide energy range and large statistics, O(104) antiprotons and O(105) positrons, will allow sensitive tests of cosmic ray propagation models and searches for exotic sources of antiparticles.

Abstract
The PAMELA experiment will be launched on-board a Resurs DK1 earth observation satellite in 2005. During the three year mission, the primary objective of PAMELA is to measure the flux of antiprotons (80 MeV - 190 GeV) and positrons (50 MeV - 270 GeV) in the cosmic radiation. The wide energy range and large statistics, O(104) antiprotons and O(105) positrons, will allow sensitive tests of cosmic ray propagation models and searches for exotic sources of antiparticles. Antinuclei searches with a sensitivity of O(10−8) in the antihelium/helium ratio will also be conducted and the light isotope component of cosmic rays and solar phenomena studied. PAMELA consists of a time-of-flight system, a transition radiation detector, a magnetic spectrometer, an anticoincidence shield, an electromagnetic imaging calorimeter with shower-tail catcher and a neutron detector.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
