The LHCf experiment is designed to measure energies and transverse momenta of neutral particles emitted in the forward region of root s=14 TeV p-p collision at +/- 140m away from the interaction point1 (IP1) of LHC. The energy resolution is confirm to be within 5% and the position resolution is better than 0.2 mm for gamma-rays with energies from 100 GeV to 200 GeV by the test beam results at the CERN-SPS.

Abstract

The LHCf experiment is designed to measure energies and transverse momenta of neutral particles emitted in the forward region of root s=14 TeV p-p collision at +/- 140m away from the interaction point1 (IP1) of LHC. The energy resolution is confirm to be within 5% and the position resolution is better than 0.2 mm for gamma-rays with energies from 100 GeV to 200 GeV by the test beam results at the CERN-SPS. LHCf has taken data at 2009 and 2010 at root s = 900 GeV and 7 TeV collision. A brief summary of LHCf operation at LHC is also reported here.
