The LHCf detector has been designed to measure the energy spectra of 7, n0 and neutrons produced very forward in the proton-proton collisions at LHC, with 14 TeV center of mass energy. The equivalent energy in the laboratory system (1017 eV) will allow significant improvement in knowledge of the mechanisms important for longitudinal development of Very High Energy Cosmic Ray (VHECR) showers, in a region never directly explored. This paper reports on the status and expected performances of the LHCf experiment, which is ready for the data taking in the very first phase of the LHC running.
