The LHCf experiment is the smallest of the six experiments installed at the Large Hadron Collider (LHC). While the general purpose detectors have been mainly designed to answer the open questions of Elementary Particle Physics, LHCf has been designed as a fully devoted Astroparticle experiment at the LHC. Indeed, thanks to the excellent performances of its double arm calorimeters, LHCf will be able to measure the flux of neutral particles produced in p-p collisions at LHC in the very forward region, thus providing an invaluable help in the calibration of air-shower Monte Carlo codes currently used for modeling cosmic rays interactions in the Earth atmosphere. Depending on the LHC machine schedule, LHCf will take data in an energy range from 900 GeV up to 14 TeV in the centre of mass system (equivalent to 1017   eV in the laboratory frame), thus covering one of the most interesting and debated region of the Cosmic Ray spectrum, the region around and beyond the "knee".
