[en] The ALICE (A Large Ion Collider Experiment) is dedicated to the study of heavy ion collisions produced in the LHC. Several concentric detectors around the primary vertex contribute to the determination of the particle tracks. The detector system closest to the interaction spot is the ITS (Inner Tracking System). ITS is composed of 6 layers of concentric cylindrical detectors. The SSD (Silicon Strip Detector) is formed by the 2 external layers of ITS. SSD is composed of 1698 frontal detection modules. The design of SSD is largely influenced by the variety of particles produced in heavy ion collisions. These modules are made of a sensitive part in silicon and of its electronic circuit. As soon as the prototype module was validated, a massive production campaign has been launched. The first 4 modules produced have been tested on the basis of an adequate beam testing procedure. The results concerning the spatial resolution, the energy resolution and the signal/background noise ratio, show that these parameters comply to the constraints imposed by the track reconstruction in Alice
