dc.description.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 Extremely High-Energy Cosmic-Rays. This is possible since the laboratory equivalent collision energy of LHC is 10(17) eV. Two LHCf detectors, consisting of imaging calorimeters made of tungsten plates, plastic scintillator and position sensitive sensors, are installed at zero degree collision angle +/- 140m from an interaction point (IP). Although the lateral dimensions of these calorimeters are very compact, ranging from 20 mm x 20 mm to 40 mm x 40 mm, the energy resolution is expected to be better than 6% and the position resolution better than 0.2 mm for gamma-rays with energy from 100 GeV to 7 TeV. This has been confirmed by test beam results at the CERN SPS. These calorimeters can measure particles emitted in the pseudo rapidity range eta > 8.4. Detectors, data acquisition and electronics are optimized to operate during the early phase of the LHC commissioning with luminosity below 10(30) cm(-2)S(-1). LHCf is expected to obtain data to compare with the major hadron interaction models within a week or so of operation at luminosity similar to 10(29) cm(-2)s(-1). After similar to 10 days of operation at luminosity similar to 1029 cm(-2)s(-1), the light output of the plastic scintillators is expected to degrade by similar to 10% due to radiation damage. This degradation will be monitored and corrected for using calibration pulses from a laser.
