Abstract :
The performance of a logarithmic detection system is investigated for the 25 MeV/u 40Ar induced reaction. The detection system consists of four parts: an axial ionization chamber (IC), a position sensitive silicon detector (PSSD), a large area PIN silicon photodiode (SPD) and a 16 element CsI(Tl) scintillator array. The energy resolutions for IC and PSSD tested with241Am (5.486 MeV) sources were 3 and 2.6% (FWHM), respectively. Fragments with Z values from Z = 2 to Z = 21 were identified in the reaction 40Ar+ 115In. A Z resolving power of Z/ΔZ∼ 44.5 (FWHM) for Z = 18 has been achieved, and the energy dynamic range for α-particles was about 2–130 MeV. A position resolution of 0.86±0.03mm (FWHM) for PSSD was obtained for the reaction 40Ar+ 27Al with 1 μs amplifier shaping time.
