  • Cosmic-ray observations of the heliosphere with the PAMELA experiment
  • 2006
  • In: Astrophysics. - : Elsevier BV. ; , s. 1848-1852
  • Conference paper (peer-reviewed)abstract
    • The PAMELA experiment is a multi-purpose apparatus built around a permanent magnet spectrometer, with the main goal of studying in detail the antiparticle component of cosmic rays. The apparatus will be carried in space by means of a Russian satellite, due to launch in 2005, for a three year-long mission. The characteristics of the detectors composing the instrument, alongside the long lifetime of the mission and the orbital characteristics of the satellite, will allow to address several items of cosmic-ray physics. In this paper, we will focus on the solar and heliospheric observation capabilities of PAMELA.

  • About Separation of Hadron and Electromagnetic Cascades in the Pamela Calorimeter
  • 2005
  • In: International Journal of Modern Physics A. - 0217-751X .- 1793-656X. ; 20:29, s. 6745-6748
  • Journal article (peer-reviewed)abstract
    • Results of calibration of the PAMELA instrument at the CERN facilities are discussed. In September, 2003, the calibration of the Neutron Detector together with the Calorimeter was performed with the CERN beams of electrons and protons with energies of 20-180 GeV. The implementation of the Neutron Detector increases a rejection factor of hadrons from electrons about ten times. The results of calibration are in agreement with calculations.

  • The PAMELA Calorimeter Identification Capabilities
  • 2005
  • In: Proceedings of the 29th International Cosmic Ray Conference, vol 3:OG1. ; , s. 305-308
  • Conference paper (peer-reviewed)abstract
    • A silicon-tungsten imaging calorimeter has been designed, built and successfully integrated in the PAMELA satellite-bome apparatus. The main physics task of the experiment is the measurement of the flux of antiprotons, positrons and light nuclei in the cosmic radiation. The purpose of the calorimeter is to separate antiprotons and positrons from the vast background of cosmic-ray electrons and protons, respectively. In this work we present the identification capabilities of the calorimeter obtained using both Monte Carlo and test beam data. We show that the calorimeter can provide a proton rejection factor of about 105 while keeping a similar to 90% efficiency in selecting electrons and positrons. The PAMELA calorimeter is therefore able to provide the identification power needed to reach the primary scientific objectives of PAMELA.
