Abstract：
A two-dimensional position sensitive multi-stage detection system with a wide dynamic range for a heavy ion reaction is described in this paper. It consists of four parts:a longitudinal electric field gas filled Ionization Chamber (IC), a Position Sensitive Silicon Detector (PSSD) (45 mm×45 mm, 400 μm), a large area PIN Silicon Photodiode (SPD) (48 mm×48 mm, 300 μm),and a 16 element CsI(Tl) scintillation detector array. The energy resolutions for IC and PSSD tested with a source ²⁴¹Am(5.486 MeV) are 3% and 2.6%, respectively. The energy dynamic range for αparticle detection is about 2-130 MeV, and the fragments with ZValues from Z=2 to Z=21 are identified in the reaction of 25 MeV/u ⁴⁰Ar+ ¹¹⁵In. The Zresolving power is Z/△ Z≈ 44.5 (FWHM) for Z=18. The position resolution of PSSD is 0.86±0.03 mm (FWHM).
