Performance of a 250L liquid Argon TPC for sub-GeV charged particle identification

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 identificationperformance of the detector using well-defined charged particles(pions, kaons, and protons) with momentum of ~800 MeV/$c$ obtained at J-PARCK1.1BR beamline.
