    The Large Hadron Collider forward (LHCf) experiment will provide the energy and transverse momentum spectra of neutral particles produced in the very forward region of p-p collision at 7+7 TeV, corresponding to a laboratory frame energy of 10 17 eV. The LHCf apparatus is composed of two independent detectors installed at zero degree collision angle from the ATLAS interaction point. To assess performance of LHCf detectors, we carried out a beam test in 2007 at the CERN SPS H4 beamline. We report results of the Arm#1 detector, using scintillating fibers for measuring shower positions, obtained from electron primary beams of 50-200 GeV, and proton primary beams of 150-350 GeV and muon primary beams of 150-200 GeV. We obtained energy resolution of electrons as a function of the primary energy. The position resolution of shower axis is obtained by using a position determined with the Si microstrip detectors. We also reconstructed the real geometry of each SciFi by the use of muon primary beams. Finally, we report an analysis of π 0 invariant mass observed by coupling the two photons decayed.
