Abstract

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 10¹⁷ 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 π⁰ invariant mass observed by coupling the two photons decayed.
