LHCf Collaboration
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 1017 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 20mm x 20mm to 40mm x 40 mm, the energy resolution is expected to be better than 6% and the position resolution better than 0.2mm 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 >8.4. Detectors, data acquisition and electronics are optimized to operate during the early phase of the LHC commissioning with luminosity below 1030 cm-2s-1. LHCf is expected to obtain data to compare with the major hadron interaction models within a week or so of operation at luminosity > 1029 cm-2s-1.
