The capability of digital pulse shape technique to acquire data from CHIMERA detection cells (Si-CsI(TI) telescopes) has been evidenced in our previous works. We have now applied this technique to the charge discrimination of the products stopped in the silicon detectors. Large area totally depleted CHIMERA planar silicon detectors (5 cm x 5 cm area, 300/[micro]m thick) in both rear and front side injection have been used. In preliminary tests full charge identification for the reaction products up to Z = 11 have been obtained for products both crossing ([DELTA]E-E technique) and stopping in the silicon detector, using a 21 MeV/u [sup.20]Ne beam at the LNS Superconducting Cyclotron in Catania. The quality of the obtained results clearly indicates that the digital signal processing approach is able to give excellent results in this application, too. Index Terms--Charged particle identification, digital pulse shape processing, multidetector arrays technique, pulse shape analysis.
