A time-of-flight scintillator system has been developed for the Pamela satellite-bome cosmic ray experiment. The Pamela main scientific goal is the measurement of the fluxes of antiprotons and positrons in cosmic rays over the large energy ranges of respectively 80 MeV-190 GeV and 50 MeV-270 GeV. The installation of the apparatus on board the Russian satellite Resurs DK1 is now in progress, the launch is scheduled for the late 2005. The TOF system will provide the fast trigger to the experiment, the rejection of albedo particles and the possibility to distinguish electrons from anti-protons up to about 1.5 GeV. The performances of the ToF and Trigger flight model systems measured using cosmic rays before the delivery for the final integration in Russia are described.

Abstract
A time-of-flight scintillator system has been developed for the Pamela satellite-bome cosmic ray experiment. The Pamela main scientific goal is the measurement of the fluxes of antiprotons and positrons in cosmic rays over the large energy ranges of respectively 80 MeV-190 GeV and 50 MeV-270 GeV. The installation of the apparatus on board the Russian satellite Resurs DK1 is now in progress, the launch is scheduled for the late 2005. The TOF system will provide the fast trigger to the experiment, the rejection of albedo particles and the possibility to distinguish electrons from anti-protons up to about 1.5 GeV. The performances of the ToF and Trigger flight model systems measured using cosmic rays before the delivery for the final integration in Russia are described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
