Abstract :
A new prototype of large area (20×20 mm2) monolithic silicon telescope with an ultrathin ΔE stage (1 μm) has been built and tested. A particular mask for the ground electrode has been developed to improve the charge collection reducing the induction between the E and ΔE stages. A special designed preamplifier has been used for the readout of the signal from the ΔE stage to overcome the problem of the large input capacitance (40 nF). A rather low energy threshold charge discrimination has been obtained. Small side effects due to the electric field deformation near the ground electrode were observed and quantified.
