LHCf is an experiment dedicated to the measurement of neutral particles emitted in the very forward region of LHC collisions. The physics goal is to provide data for calibrating the hadron interaction models that are used in the study of very high-energy cosmic-rays. This is possible since the laboratory equivalent collision energy of LHC is 1017 eV. Using the two independent detectors containing imaging sampling shower calorimeters, LHCf can determine differential cross sections of 0’s and neutrons in the pseudorapidity range >8.4. These measurements can set critical constraints for the models currently used and to be developed in future. The LHCf detectors are already installed in the LHC tunnel and ready to take data when the LHC starts operation in late 2009. LHCf will complete data taking at the early phase of the LHC commissioning at ps = 10TeV (5×1016 eV in labo. frame) in 2009 and come back when the LHC reaches the maximum energy ps = 14TeV.

Abstract
LHCf is an experiment dedicated to the measurement of neutral particles emitted in the very forward region of LHC collisions. The physics goal is to provide data for calibrating the hadron interaction models that are used in the study of very high-energy cosmic-rays. This is possible since the laboratory equivalent collision energy of LHC is 1017 eV. Using the two independent detectors containing imaging sampling shower calorimeters, LHCf can determine differential cross sections of 0’s and neutrons in the pseudorapidity range >8.4. These measurements can set critical constraints for the models currently used and to be developed in future. The LHCf detectors are already installed in the LHC tunnel and ready to take data when the LHC starts operation in late 2009. LHCf will complete data taking at the early phase of the LHC commissioning at ps = 10TeV (5×1016 eV in labo. frame) in 2009 and come back when the LHC reaches the maximum energy ps = 14TeV.
