PAMELA - A payload for antimatter matter exploration and light-nuclei astrophysics

The PAMELA experiment is a satellite-borne apparatus designed to study charged particles in the cosmic radiation with a particular focus on antiparticles. PAMELA is mounted on the Resurs DK1 satellite that was launched from the Baikonur cosmodrome on June 15th 2006. The PAMELA apparatus comprises a time-of-flight system, a magnetic spectrometer, a silicon-tungsten electromagnetic calorimeter, an anticoincidence system, a shower tail catcher scintillator and a neutron detector. The combination of these devices allows antiparticles to be reliably identified from a large background of other charged particles. This paper reviewsthe design, space qualification and on-ground performance of PAMELA. The in-orbit performance will be discussed in future publications. (c) 2006 Elsevier B.V. All rights reserved.
