which also provides the trigger signal, a solid state magnetic spectrometer [3,4], surrounded by an anti-showers are not fully contained in the calorimeter. The whole detector can discriminate protons and electrons from their antiparticles and provide energy ARTICLE IN PRESSmeasurements; also Z41 nuclei may cross the entire spectrometer and consequently can be detected. Antimatter acquisitions will cover the energy range 80MeV–190GeV 0168-9002/ $- see front matter r 2005 Elsevier B.V. All rights reserved. doi:10.1016/j.nima.2005.10.014 Corresponding author
