The performance test of a CsI(Tl) crystal (70×27×23 mm³) was performed by applying the pulse shape discrimination technique for identification of light charged particles . The crystal is coupled to a photomultiplier tube during an experiment with ⁶He beam. The pulse waveform is fully recorded by employing a high precision digital oscilloscope. The fast and slow gates are used for the pulse shape discrimination and the best values for the gate widths were determined to be 0.5 μs and 1.67 μs, respectively. The ⁶He, ⁴He and ³He are successfully discriminated with this technique.
