Abstract

The time-projection chamber (TPC) with triple gas-electron multipliers (GEMs) is designed for the large-acceptance multipurpose spectrometer (LAMPS) at the new radioactive ion-beam facility RAON, a pure Korean term for the accelerator complex, in Korea. The simulation environment has been set up to test the performance of the designed chamber, and the software package for analysis has been developed. Particle identification has been demonstrated to be possible up to 2 GeV/c in momentum for particles with the charge number 1 and 2 by using the simulated heavy-ion events. The transverse-momentum resolutions are expected to be about 2% for protons and about 1.3% for pions in the relatively high-momentum region. The total reconstruction efficiencies are estimated to be about 90 and 80% for charged pions and protons, respectively.
