Abstract: In order to identify the charge number Z of the projectile like fragments emitted from the dissipative heavy ion reactions,a set of ΔE-E telescope has been constructed,which consists of two ionization chambers for ΔE1 and ΔE2 in series followed by a position sensitive semiconductor silicon detector to deposit residual energy E. The trajectory of the incident particles is parallel to the direction of the electric field in the ionization chamber. The detector system has a lower energy detection threshold,compact configuration and capability against the disturbance from the electromagnetic wave. The charge resolution of Z/ΔZ≈30 of the telescope has been achieved in an experimental measurement of excitation functions of dissipative heavy ion reaction.
