The PAMELA satellite experiment will be launched on-board a Resurs DK1 earth observation satellite towards the end of 2005. During the three year mission, the primary objective of PAMELA is to measure the flux of antiproions (80 MeV - 190 GeV) and positrons (50. MeV - 270 GeV) in the cosmic radiation. The wide energy range and large statistics, similar to 10(4) antiprotons and similar to 10(5) positrons, will allow sensitive tests of cosmic ray propagation models and searches for exotic sources of antiparticles, such as the annihilation of dark matter particles. The PAMELA experiment contains two anticoincidence systems built from plastic scintillators read o ut by photomultipliers. One system surrounds the permanent magnet spectrometer and the other surrounds the volume between the first two time-of-flight layers. The pre-flight performance of both anticounter systems has been studied using data from ground tests of PAMELA.
