Astroparticle physics at LHC: The LHCf experiment ready for data taking

LHCf is a high-energy physics experiment designed to study the forward production of neutral particles in proton-proton collisions at the LHC. The set-up consists of two small calorimetric systems symmetrically placed 140m away on both the sides o f the ATLAS interaction point. Results from the experiment will provide valuable information to the calibration of the nuclear interaction models used in the Monte Carlo codes for air-shower simulations, which are of great importance for present and futur e ground-based cosmic-ray experiments. In particular, since LHCf will start taking data in the first phase of operation of the LHC (during the beam commissioning phase at 5+5TeV energy) and will complete its data taking at the beginning of the 7+7TeV runs (laboratory equivalent collision energy 10^1^7eV), it will span an energy range up to the region between the ''knee'' and the GZK cut-off of the cosmic-ray spectrum.
