    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 studies of extremely high-energy cosmic rays. LHCf can discriminate the existing models by the measurement of gamma-rays. Furthermore, because measurement of neutrons gives information of elasticity, it is complementary to the measurement of gamma-rays. The performances of the LHCf detectors for hadron showers were investigated at the CERN SPS H4 beam line in 2007. The tests were performed using 150MeV and 350 GeV protons. The detection efficiencies of 11% and 26 %, the energy resolutions of 21% and 27% are obtained for each energy. These results are in agreement with the results of full Monte Carlo simulation. We also simulated for the energy range at the LHC operation and found the efficiency and resolution are almost independent of incident energy over 1 TeV. At 3TeV, the detection efficiency and the resolution were about 20% and 40 %, respectively. We also found that the number of shower particles contained in a neutron event is approximately 30% with respect to that of an electron induced shower with the same energy.
