In ultra-relativistic heavy ion collisions, the centrality of a collision is measured by the total charged particle multiplicity while the distribution of these particles in rapidity space is a reflection of the thermodynamical conditions and the hadronization processes in the collision volume. As one of the R & D projects for the PHENIX experiment at RHIC, a double-sided Si $p sp+nn sp+$ junction pad detector is developed. One side of the detector measures the particle distribution and the other side the total multiplicity. A prototype detector made of 7.6 cm diameter, 300 $ mu$m thick Si wafer with 512 pads on one side and 16 larger pads (petals) on the opposite side has been successfully developed, constructed and tested, both in-beam and off-beam at the Brookhaven National Laboratory. The detector, the results as well as the Monte-Carlo simulation comparisons are presented.
