Abstract

The uncertainty of hadron interaction models that are used in Monte Carlo simulations have caused some systematic errors in the energy reconstruction and the determination of composition of ultra high energy cosmic rays. The uncertainty of the models is due to the lack of the experimental data on the nuclear interactions in the energy region over 2×1014eV. The LHCf experiment will provide crucial calibration points at the laboratory equivalent energy of 1017eV, that are indispensable for the hadron interaction models in the ultra-high energy region. The production spectra of photons, neutral pions and neutron will be measured in the very forward region of a LHC interaction point. The first data will be taken during beam commissioning of the LHC with 450GeV+450GeV proton-proton collisions, which is scheduled to start at the end of 2007. The data set will be taken with 7TeV+7TeV collisions, corresponding to 1017eV cosmic ray collisions in the laboratory frame. The LHC is scheduled to start 7TeV+7TeV collisions in the Spring of 2008. In the meantime the preparation of the LHCf experiment is ongoing. The Arm#1 detector was fully assembled in July 2006. The Arm#2 detector was fully assembled in April 2007.
