PAMELA (Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics) is a satellite-borne experiment designed to study charged particles in the cosmic radiation over the largest energy range ever achieved. The apparatus is composed by a magnetic spectrometer, to determine the charge of the particles, an electromagnetic calorimeter and a neutron detector (ND), which perform the particle identification; in addition, an anticoincidence system, a time of flight (TOF) system and an additional shower tail catcher scintillator (S4) located below the calorimeter complement the instrument. The system composed by the electromagnetic calorimeter, the S4 and the ND will look for events with high energy release (more than 100 GeV) in the calorimeter, and with a larger field of view than that of PAMELA (~ 900 cm2sr). In this work we will show preliminary results concerning the performances of ND and S4 detectors coming from data collected during ground tests (January-May 2005) with PAMELA in final configuration.
