The performance of the LHCf detector for hadronic showers

The Large Hadron Collider forward (LHCf) experiment has beendesigned to use the LHC to benchmark the hadronic interaction modelsused in cosmic-ray physics. It measures neutral particles emittedin the very forward region of the LHC p-p or p-N collisions. Inthis paper, the performances of the LHCf detectors for hadronicshowers was studied with MC simulations and beam tests. Thedetection efficiency for neutrons varies from 70% to 80% above 500GeV. The energy resolutions are about 40% and the positionresolution is 0.1 to 1.3 mm depending on the incident energy forneutrons. The energy scale determined by the MC simulations and thevalidity of the MC simulations were examined using 350 GeV protonbeams at the CERN-SPS.
