Application of ΔE-E Telescope in ⁹C Fragmentation Reaction

For studying the halo structure of ⁹C, a set of ΔE-E telescope detector was applied in the experiment of ⁹C fragmentation reaction carried out at the facility of Radio active Ion Beam Line in Lanzhou (RIBLL). The detector was used to measure the fragments produced in the reaction. The principal aim is to solve the crosstalk between silicon strips and the energy calibration of silicon strip and CsI(Tl) crystal. Using the induced signal of the saturated signal produced by heavy ion punching through the silicon strip, the deposited energy was calibrated. Combining the simulated result and experimental data, a series of energy points were obtained to calibrate the CsI(Tl) crystal. The ion track was reconstructed by position information both in silicon strip and in CsI(Tl) crystal which were coincident with each other for one ion. Finally, the real physics event was obtained.
