As a result of a collaboration between SGS-Thomson and INFN, a Monolithic Silicon Detector Telescope with Delta E/E of 4 x 4 mm(2) with an ultra-thin Delta E stage (1 mu m) has been recently presented as a tool to identify low-energy heavy ions. The good performances obtained in the charge identification are anyway limited by the relatively small active area. We report on two new larger area Delta E/E telescopes. The first one, a five strip detector with each Delta E/E strip 3 x 4 mm(2) and a common E stage, has given on-beam good results. The second one, a 20 x 20 mm(2) active area, is under test and is limited by the high capacitance of the Delta E stage (40 nF) requiring a suitable front-end electronics, presented in a different communication.
