Description
A two-dimensional position sensitive multi-stage detection system with a wide dynamic range for heavy ion reaction has been developed. It consists of four parts: a gas filled axial ionization chamber (IC), a position sensitive silicon detector (PSSD) (45 x 45) mm, 400 μ), a large area PIN silicon photodiode (SPD) ((48 x 48)mm, 300 μm) and the 16 element CsI(Tl) scintillation detector array. The energy resolutions for IC and PSSD tested with α-source of 241Am(5.486 MeV) were 3% and 2.6% respectively. Fragments with Z values from Z = 2 to Z = 21 were identified in the reaction of 25 MeV/μ 40Ar + 115In. The Z resolving power was Z/ΔZ ≅ 44.5 (FWHM) for Z = 18. The position resolution of PSSD was (0.86 +- 0.03) mm (FWHM). And the energy dynamic range for α particles was about 2-130 MeV
