A CsI(Tl) detector array for the measurement of light charged particles in heavy-ion reactions

摘要

An array of eight CsI(Tl) detectors has been set up to measure the lightcharged particles in nuclear reactions using heavy ions from the PelletronLinac Facility, Mumbai. The energy response of CsI(Tl) detector to$lpha$-particles from 5 to 40 MeV is measured using radioactive sources andthe $^{12}$C($^{12}$C, $lpha$) reaction populating discrete states in$^{20}$Ne. The energy non-linearity and the count rate effect on the pulseshape discrimination property have also been measured and observed thedeterioration of pulse shape discrimination with higher count rate.
