We have constructed a liquid Argon TPC detector with fiducial mass of 150 kg
as a part of the R&D program of the next generation neutrino and nucleon decay
detector. This paper describes a study of particle identification performance
of the detector using well-defined charged particles (pions, kaons, and
protons) with momentum of ~800 MeV/$c$ obtained at J-PARC K1.1BR beamline.
