One of the unique features of the E814 experimental setup at the BNL-AGS, is its nearly 4$ pi$ calorimetry. Calorimeters, however, do not provide information on the nature of particles and their multiplicity. Particle identification is important to understand the expansion phase of the hot nuclear matter produced in relativistic heavy ion collisions. In the present 814 experiment the charged particle multiplicity is measured at forward angles only, by a Si pad detector. The addition of a similar Si detector in the target rapidity region, overlapping the Target Calorimeter, is being considered. Initial calculations have shown a possibility of particle identification by using the signals from a silicon detector and from the highly segmented Target Calorimeter. In this thesis, the potential for particle identification of an upgraded silicon multiplicity detector at target rapidity is evaluated using a silicon surface barrier detector and part of the Target Calorimeter. The measured response is compared to the predictions of the event generator HIJET followed by complete tracking using the code GEANT.
