The LHCf experiment is a forward experiment of LHC. The two LHCf detectors, each composed of a pair of sampling and imaging calorimeters, have been installed at the forward region of IP1 to measure energy and transverse momentum spectra of neutral particles emitted in the very forward region of LHC collisions (η > 8.4). The operation at 900 GeV and 7TeV pp collisions has been completed in the middle of July 2010. We present some preliminary results in this paper. PACS 13.85.Qk-Inclusive production with identified leptons, photons, or other nonhadronic particles. PACS 13.85.Tp-Cosmic-ray interactions.
